Absolutely.

The approximate V/S when the FDs came back online was 1500fps. Even if neither F/O followed the correct procedure - which was to disable them - you'd hope that the PF would ignore them as a matter of course until things were stabilised.

The reason I'm sceptical about the FDs being responsible for the NU inputs is because the inputs continue, and indeed intensify, after the FDs go away again - as well as the fact that he continues to feed in short bursts of ND even after the actual V/S starts falling away dramatically. I have to admit the possibility that the PF did indeed choose to follow them, but I remain to be convinced.

It appears more likely to me that he was chasing the pitch on the artificial horizon as the aircraft entered the buffet at the apogee of the climb and thence into full aerodynamic stall.
