Further to the above post, I looked back through GM’s statements.
The timeline written by the Tapas Group on the kids book is in his 9 September statement. One of the notes, attached below, specifically asks “? Did he check”. This is right under the 9:10-9:15pm check.
I wonder why this question was asked?
Is it possible he met JW on the way to 5A not on the way from it?
It might be unpopular to say so, but I must admit the idea that GM didn't really carry out the check has crossed my mind too. Specifically, that he intended to the check, got to the gate and saw JW, decided to stop for a chat, and then returned straight to dinner. Either forgetting about the check or just to rush back for the starters.
The one thing that always puts me off this idea, is that a parent would potentially put the investigation at jeopardy by lying that he'd set eyes on MM during the 9.05 check when she might feasibly have already been taken by then. All in order to avoid looking bad. But that scenario can possibly be explained by other events, which I'll come onto. Unlike MO's account (which I find easier to disbelieve), which tells us almost nothing about when someone might have struck, GM's sighting of MM at 9.05 is crucial in establishing the window of opportunity.
As you point out, if we assume GM never entered the apartment, a number of other things start to make more sense. Particularly that if someone was watching the apartment, it makes most sense to enter as soon as the parents had left. And it would certainly explain HCWs apparent "coldness" to the parents if his evidence effectively proves they lied, as well as HCW's comment regarding something only CB could know.
You are correct that in his first statement, GM claimed to have used his key to enter 5A (via the front door) before changing his story in his second statement to say he went through the unlocked patio door. Perhaps it was just stress/confusion but it is strange why he claimed to have gone through the front door initially, particularly when he'd already admitted in his first statement that the patio door was always unlocked and that MO entered 5A using that door:
"
At about 21.30 his friend Matt (member of the group) went to the apartment, where his children were and on his way went to the witness' apartment, entering by means of a glass sliding door that was always unlocked and was located laterally to the building. He entered the bedroom, he observed the twins and he did not even notice whether Madeleine was there"
Continuing to describe MO's check in his first statement, he then curiously says this:
"...as everything was calm, the shutters were closed and the door to the bedroom was ajar as usual. "After that Matt returned to the restaurant."

So, we can deduce at this point in time, GM was under the impression, from whatever conversation (or second hand communication) he had with MO after the event, that MM's door was not open and the shutters were closed! This is important because he is effectively admitting, at this point in time, he was confident that whatever happened to MM, must have taken place after MO's check. Therefore, it might then explain why he felt confident enough to claim seeing MM at 9.05 even though he hadn't. When you consider the initial timeline the Tapas group had put together, it's clear that the detail of MO's check was known about before GM had made any comment about what he actually saw during his check. MO already told GM at dinner that "all was well" in 5A which would have led GM to believe his check at 9.05 was irrelevant anyway, even without the further confirmation he would have presumably sought after the alarm was raised.
Another oddity from GM's first interview, is that he doesn't once mention the door to MM's room being more open that he'd left it. And given that he tells us that when MO did his check "the door was ajar as usual", why on earth wouldn't he have mentioned that the door was not "ajar as usual" when he went in there? That is odd! Alternatively, perhaps he didn't mention it thinking it was irrelevant, confident that it had nothing to do with MM being taken and that she had perhaps opened it. Still, it should have been said if that's what he saw.
In GM's second interview, he has obviously now learned more about MO's account, and specifically of MO's claim that the door was actually open and the shutters may have been up. Only now does GM say that the door was also open upon his check. One of the more intriguing comments from his second interview concerns him clarifying what he'd previously said about MO's check:
"The deponent had had the wrong idea that MATHEW had seen the bedroom external blinds closed when he was there at 21H30, the reason for that was that he thought the disappearance would have been happened between 21h30 and 22h00..."
So, he's effectively saying he just asumed the blinds were closed because he believed (at that time) that MM must have been taken after the 9.30 check based on MO saying that all seemed fine. It then continues:
"...it being that, actually, he is [?] convinced that the abduction occurred in the period understood to be between his visit at 21h05 and MATHEW'S visit at 21H30."
P.J. POLICE FILES: GERRY MCCANN'S STATEMENT 10 MAY 2007
So what he's saying, is that in contrast to his initial thoughts, he's now convinced that the "abduction" must have taken place prior to MO's check and the shutters were in fact open at this point. Which conveniently fits the narrative of Tannerman being the culprit. This is consistent with what
@mrjitty was saying about them contaminating each other's accounts. They are tailoring their story to be consistent with what they have learned from other people.
If he had initially lied about setting eyes on MM at 9.05, now would have been the time to come clean. But, if he honestly believed Tannerman was the intruder, and that this sighting was around 10 mins after he claimed to do his check, he might think it not worth risking admitting he lied. Particularly if he could claim the intruder might have already been in the apartment while he was there, hiding behind the door, something he later claimed to have had "a feeling" about.
Again, this is not necessarily my opinion of what actually happened, just pointing out possible options and further inconsistencies in the accounts.
