Correct me if I'm wrong and I'm sure I could be....

 

RWD... They push the car around the corner.. Get over steer with too much power.. Lift off and it stops pushing/stops over steering.

 

FWD... They pull the car around the corner.. Get under steer with too much power.. Lift off and the car stops pulling and the rear wants to get in front.

 

This might be slightly simple in it's idea (ie lift off too quickly in a RWD and it might want to snap the opposite way), but I think that's the general theory.

You can get lift-off oversteer in any car, it happens because of weight transfer. When you lift, the car slows down, which transfers weight to the front. That gives the front more grip and the rear less. A more extreme version happens if you brake while cornering. You can use this to help the car turn into a corner, by coming off the brakes slightly after you turn in to give the front more grip as you turn into the corner. This is called trail braking (not a good idea to try it unless you know what youre doing though!).

as an added bonus, lift off oversteer can be much worse on permenant 4wd cars. In additional to any simple weight transfer which should 'normally' be more predictable when on the egde, lifting of in a 4wd can cause torque from the fronts to be transfered to the rears (as far as my understanding of it goes) where they rapidly (split second) loose traction and the car can do a spontaneous 180 spin, That's proper lift off over steer lol that can bite you bad
