No it isn't.It’s impossible to understand how she thought they were on the opposite side of the street and that they didn’t see her.
There was no "collusion" regarding JW encounter with GM returning to the tapas. He is a truly independent witness.
There is no doubt that JT left the tapas prior to GM returning. She saw G and J standing together in the street and she saw the man carrying a child crossing the road from the direction of the apartment from where it would be later found a child had been abducted.
JT saw what she saw and that is on record in the PJ files. GM and JW corroborated they were having a conversation in the street at that time when JT passed them by. That too is in the files. They neither saw her or the man at the top of the road which is also on record in the files.
The timing is also recorded in the files for the three holidaymakers; the fact that the two in conversation didn't see the third passing them by is not extraordinary particularly if they passed where the pavement broadens into the lane behind the apartment block.
