...following the elevator demand.
If the SS is neutral, the command is for 1 G. The aircraft was stabilized at 1 G in the stall. Why for gosh sakes would the THS have to move at all?
If it did, tending to create a load factor of less than 1 G, a situation Mach' alludes to, the elevator would have to then move NU to maintain the neutral, 'hands off' 1 G SS command.
THS may not necessarily follow SS input direction. Example:
In a dive recovery with the SS full back, load factor will be +2.5 G (1.5 over neutral) if the airspeed is 'adequate' to achieve +2.5 G (There will be, additionally, some MLA control surface action). If the aircraft continues to accelerate in the dive recovery, the THS (and possibly elevator) will bias in the ND direction,
opposite the SS input, to prevent the G from exceeding 2.5 as the airspeed increases. This not a ND command, just a reduction in NU to prevent over-G but it is movement opposing the command input direction. Depends on airspeed.
Not that you would get there, but I would guess that if full forward stick were providing -1 G, and if the aircraft were accelerating, the THS would bias in a NU direction to prevent exceeding - 1 G (severe discomfort & nausea not withstanding).
(Of course in Direct, instead of Alternate, you can get even more G...in trade for the potential detaching of parts of the aircraft.)
