I directed you to a BEA graph that clearly shows small THS movements between A/P disconnect and 02:10:51, both in the FDR trace and the simulation trace.
At 2:10:51, when the THS started its NU trim, the pilot was about to run out of elevator, and would have Stalled.
At 2:10:51 the elevator was at 1.6 degrees NU. It did not exceed 10 degrees NU until 02:11:37 and reached 30 degrees (full travel) at 02:11:45.
Why did the THS not follow the PILOTS NU in the climb?
It did, see above.
