However, why would Airbus programme the systems to abandon functions and leave the stabiliser control surfaces in such an extreme setting.
The THS setting is not "programmed" to be left at an extreme setting - the autotrim was doing it's job perfectly and the THS setting was the natural result of the low speed, the a/c was in trim.

You've read the report; now go read the FCOM! You're wasting your time trying to understand what happened until you do.
Spoken like a PPL holder! Your comment
THS freezes while in normal law in some situations, but going below Vls is not one of them.
while arguably perfectly accurate denies the fact that the THS autotrim stops when AOA-protection is active, which will also be below V
LS.
For those interested the THS setting in this situation cannot be increased (nose-up) by autotrim or trim wheel movement.
