Every time both rear tires go over a bump, and the sway bar rotates, the valve will move.

I assume it reacts slowly enough that the LAD does not affect handling, and in effect the valve "averages out" all the bumps to determine if the car is too low or too high.

I imagine it is always trying to keep up with all the bumps it experiences, but since it can't (by design) the end result is a smooth adjustment of the rear ride height.

But even if the end result (output) is smooth, the input valve movement is not. Still, the range of motion is less than the strut, but the velocity might not be.
