Yes, again... He never applied enough nose-down input to have a significant effect..
If you wish, zoom again (200%) in segment 2:12:30 to 2:12:45. The average input value sent to computer was clear ND. But the elevator doesn't rotate more than half NU and THS doesn't bother from max NU.
Doesn't matter the law, if PF demand ND rotation A/C should start rotate that direction not opposite, especially under stall warning. By the way, maybe you noticed that stall "wakes up" with each ND input 2:12:35 and 2:12:40.

See the video below at 25:08, how much time was required in this case?
