Until you are using the manual wheel which is overriding it.
Recorded (and displayed) speed dropped (LHS and stand-by) due to ice, down to 60 kt (false) during one minute and come back to 215 (real), then 185 (real). They heard those stall warnings... no overspeed.
We don't know that the roll to the right happened because of the stall or just before it. The report mentions the roll, the pitch up and then the stall warning in that order. Perhaps the PF merely thought the a/c was rolling and and pitching down, having forgotten that the engine thrust was set at a lower level when AT disconnected.
