No.
How do you know? For when I investigated it those two pieces are designed to move at times together and at other times independently. One can prove this by look at the latch of most modern doors and you will be able to move both together if one was to press the latch bolt but the other non bevelled bit can move independently without moving the latch The second bolt is there to prevent slipping a plastic card or whatever behind the latch bolt.
Now when Goncalo's security expert examines the front door he talks in Portuguese and we read the closed captions (from memory), but IMO Alexandre Simas has his words translated incorrectly. He talks of "screw" which I believe now to be "bolt", for there was no photograph showing a proud screw but we do have a latch with the latch bolt lock.

43.28 – With the help from one of the major experts from the Scientific Police, who worked for the Polícia Judiciária, Alexandre Simas, Gonçalo Amaral intends to prove, first, that it was impossible for the child to be abducted, starting by demonstrating that the indications prove that the apartment’s window and door were not forced.
43.47 - How does one open a door like this, without the key?
Alexandre Simas
Expert (Former Polícia Judiciária)
43.51 – This type of apartment door, normally there are only three possibilities: to extract the lock’s cannon, which didn’t happen, or it would have been reported; a false key, a copy or one that was used without permission;
or using a malleable material, as long as it’s not locked, it’s introduced, and it makes the lock go back inside. But when it goes in, even if it did, it would hit this screw. If it hits the screw, no matter how much I force it, it doesn’t jump to open the lock for me."
I'm sure now where it says "screw" the right word should have been "bolt". When talking locks a bolt is not a threaded bolt with a head but a piece of metal that is movable.
But the interesting thing is the this proves beyond a doubt that the rim latch on 5A had been modified in such a way that "will NOT be able to move both together if one was to press the latch bolt".
In the latch on the front door of 5A the two pieces of metal moved independently at all times
