They have to be compared to each other in order to figure out if the car is moving or not. ie: If the ABS see all wheels are "stopped", it'll assume that the car is at a complete stop; it wouldn't know if the car is still moving. On the other hand, if it sees one wheel is locked while 3 are still moving, it'll know that wheel is locked up, and attempt to "correct" it.
