TTO in my experience is like grabbing the hand brake in mid corner (I learned this racing datsun 510's on ice in Edmonton).

If the rear tires are at their traction limit with cornering force, and then you ask them to do braking as well- (which is what you are doing when you let off the gas with the clutch engaged) - bingo, total loss of traction at the rear. Front tires are still fine, they have not been asked to do braking as well as cornering, so you pivot very quickly around the front tires!

That's why giving a small! amount of gas will work: you are removing the braking load from the rear tires and are letting them just do the cornering job like the fronts.
