The sliding in the video with the Clio RS is known as lift-off oversteer. It's when the car undergoes a weight transfer to the front due to "lifting-off" off the accelerator. The front becomes loaded, the rear becomes light and loses traction. Then it's a situation where you control the cars attitude in the turn with the throttle, steering and occasionally, the brakes.
