Hi studi,
They would not have had to wrestle forcefully the yoke forward, while needing one hand to control a misbehaving autothrust system.
All they needed to do was to disengage the autothrust and advance the thrust.
How can 3 crew members watch the speed decay to Vref -20?
Why did no one press the TOGA switches?
Alternate Law would not have saved that crew either.

"The first officer responded immediately to the stick shaker by pushing the control column forward and also pushing the throttle levers forward. The captain however, also responded to the stick shaker commencing by taking over control. Assumingly the result of this was that the first officer’s selection of thrust was interrupted. The result of this was that the autothrottle, which was not yet switched off, immediately pulled the throttle levers back again to the position where the engines were not providing any significant thrust. Once the captain had taken over control, the autothrottle was disconnected, but no thrust was selected at that point. Nine seconds after the commencement of the first approach to stall warning, the throttle levers were pushed fully forward, but at that point the aircraft had already stalled and the height remaining, of about 350 feet, was insufficient for a recovery."
