Yes, it stops it being over-revved by the back wheel turning over the engine - kind of like wheelspin but in reverse!
The backwards torque on the clutch makes the centre hub slide up the ramps (usually 45deg, sometimes with ball-bearings in between) and this makes the centre pop-outwards and thus engaging the clutch. Once the torque goes, the centre is able to slide back down the ramps, and the clutch is let out again.
Very simple really!
I've attached a picture of the back of the slipper clutch centre hub, where you can see the ramps. They have grooves to run ball bearings inside as well.
