Here is a set of graphs illustrating the association between certain pilot commands, Pitch variation, and Stall Warning OFF/ON/OFF, and the consequences on the confusion in the cockpit.
Unfortunately, the confusion took place during the time window in which the recovery was still possible (35000 ft to approx 6000ft).

a) the STALL WARNING stopped during the STALL, with a confusing effect - the a/c was still in STALL.
b) the STALL WARNING started during the transition from STALL to NON-STALL, with a confusing effect - the pilot commands were ND, or lower Thrust, to take the a/c out from the STALL, and the start of the STALL WARNING meant that the commands were wrong, and so they stopped/reverted the commands.
