Once PF had commanded a pitch attitude which resulted in a real (not just spuriously indicated) speed decay - even if he didn't touch the side stick again - the FBW computers would attempt to maintain that trajectory by moving the elevators and hence the stab trim.

Even if the pilot had let go the stick following his first input of NU, the a/c would have flown into STALL. This means the pilot is constantly responsible for Pitch, but cannot relax the stick either, setting up a lethal and terminal misunderstanding of flight path in an upset a/c. Peachy.

Alternate Law in upset is absurd. And deadly.
