The A330 simulation referred to by that poster involved a full forward SS input but 'the nose did not come down'.
If the SS input did not change the existing dynamic, why would there be a requirement for the autotrim to change even in ALT2?
Autotrim is a 'TRIM' function for dynamic pressure changes which would alter the existing 'G'/longitudinal command and doesn't 'necessarily' follow the direction of SS movement unless the SS has some effect on the existing flight conditions.
These are two very different simulations, neither of which can positively be confirmed as representing either aircraft faithfully. Both posters may well want to monitor the SD FLT/CNTL page the next time they get a chance to do this.
The other side of the coin is that one or both of the simulations MAY actually represent the aircraft characteristics and certainly will up to the point that actual stall flight data was accumulated and incorporated in the simulator flight package. Beyond that, well there are a number of posters here that are sure they know what will occur...
