Viper, there's no such thing as live testimony. There's testimony, and that's it. There isn't evidence that isn't shown in the court, and then miraculously appears against the accused.
The phone/iPAd/Whatsapp information that was read out in court was submitted as evidence.
You will notice that every piece of telephone or message evidence that was read out in court had to be given a reference no. ZZ1, ZZ2 etc etc.
The big stack of paper was the printouts that contained these messages. The rest of the messages were handed in, but they are not being used as evidence. Roux has to be given the opportunity to challenge every piece of evidence before it gets anywhere near OP. That's his job, he's OP's defense lawyer. Roux then asked Francois Moller to look at some other messages, and these were given a reference no. as well, as again these are the only ones being used as evidence.
You can't hold back a piece of evidence that the defense lawyer hasn't been able to challenge and spring it on the accused, it doesn't work like that.
Think of it like this, it would be the equivalent of prosecution displaying a purse in court, which needs to be challenged by Roux. Roux discusses the purse on cross-ex and the purse is submitted as evidence. The PT can't later bring the purse back once the accused is on the stand and say, 'Sorry Mr Pistorius, you're lawyer discussed the purse, but we now need to question you on these suspicious looking coins inside'.
If it hasn't been introduced to Roux it won't be introduced to OP. :facepalm:
