Any release of the stick, not to talk about push command, would have provoked an immediate ND change in the attitude.
Direct law would not have allowed to go that easily to the stall and would have favorized an exit from that stall.

HazelNuts39: In the two instances that the PF released the stick, the elevator responded and the airplane promptly pitched ND.

Quote CONFiture: And nothing to compare with what would have been obtain in direct law in terms of ND movement and AoA reducing in order to achieve stall exit.
@HazelNuts39
To emphasis CONFiture´s position: Elevator only reduced from full NU to 15° NU (time 02:12.46 and 02:13:55) after a significant time delay, whereas in direct law the elevators would have responded immidiately according to the SS position, meaning SS neutral, elevators neutral, SS Full ND (02:12:32, 02:13:40) elevators equivalent full ND. Just superimpose the SS command over the elevator position and the outcome is obvious.
