It's both. If I leave the trim in neutral and lift the stabilator (which I do during my walk-around), the anti-servo tab rises in the same direction at a steeper angle -- when the trailing edge of the stabilator rises, the trailing edge of the anti-servo tab rises further, and when the trailing edge of the stabilator goes down, the trailing edge of the anti-servo tag goes down further. That's the damping part, and it depends only on the elevator input from the yoke. The elevator trim wheel changes the default position of the anti-servo tab so that it can also act as a trim tab, but it still moves up and down with the stabilator (just by different amounts).
