The answer is that the fronts require additional signal voltage to open the solenoids, while the rear requires a lowered signal voltage to accomplish the same thing; it's all in the ride computer.
Another difference in the Mark VIII setup (unless you have a very early '93) vs. the Mark VII is that the Mark VIII makes height adjustments at the front first, then the rear; the Mark VII does it the other way. For sensor lowering info on the Mark VIII, see: http://tinyurl.com/g9cf5
