A cabin crew member probably wouldn't have noticed anything unusual about changing the altitude and starting a descent with the AP on.
However, wouldn't it be suspicious if the captain tries to get back in the flight deck and the FO doesn't let him in anymore?
The emergency code? The banging on the door? No reaction from the FO?
All it takes is one crew member to open the flight deck from the inside.
Note: I'm not saying that having a cabin crew member in the flight deck is the solution for this. There will always be other ways for people with bad intentions. And with this, I don't want to imply that the cause of the crash is proven. The investigation is still ongoing.
