If you're talking about the differential, the system applies the brakes to the spinning wheel to make the diff send power to the OTHER side. Therefore, you still have usable power to put down.

...as opposed to say, a traction control system which retards ignition in order to just get the car back under control.

One is a safety system and the other is a performance tool. It's simply a way of using existing electronics (ABS equipment) to accomplish a similar task to a LSD (though not as skillfully)
