Normal and Alternate Law pitch commands are for *flight path*, not G.
(which is, I believe, the crux of CONF iture's idea behind the THS trying to maintain flightpath even if the PF let go - in all honesty the answer to that is outside my sphere of knowledge)
HAL does this, not the pilot unless in one of the myriad of control laws.
The computers can't do it unless the pilot tells them to.
(and in this case the pilot was still trying to command a climb for almost a minute after the aircraft had stalled and begun to descend - the computers were simply trying to comply because they weren't specified with this scenario in mind)
My feeling is that all 'bus drivers need to see what HAL is doing to "help" them from getting into problems. All the "help" can hurt you when flying where you are not used to.
You can see what autotrim is doing at any point by looking at the trim wheel. Of course, that's no good if the pilot hasn't been told where to look...
