Evidence would be his ham handed handling of the a/c in manual.
Just as logically explained by the fact that he had no training or practice in manual handling.

One could say he was merely rusty in ALT, but one could also say he thought NORMAL LAW still obtained for flight, and the ship still responsible for smooth.
Then - again - he should have been listening

If PNF was seriously asking "What was that?" re: STALLSTALL, and PF did not even mention it, why would you say he saw amber "ALT LAW" on the screen? One can make no suppositions in the absence of even basic conversation re: CRM.
Indeed - we don't even know if "What was that?" referred to the stall warning.

As to why he did not question why the a/c was "handling different", are you serious? He didn't know it was "handling" at ALL and I suggest he was unable to discern the simple matter of LAW differentiation on the "fly".....
He didn't need to - he should have made small, gentle corrections. Instead he bashed the stick around like he was attempting a crosswind landing. Even in Normal Law this would have brought the aircraft to the edge of stall - those inputs were not only in excess of what was required, but also in excess of what was sensible. Discussion of control laws is a red herring, because it has absolutely no bearing on why those inputs were so inappropriately excessive in the first place.

First and foremost - even if he was in Normal Law, the attitude he was trying to command was completely inappropriate at cruise level.
