I have been autocrossing on and off for 40 years in FWD, AWD and RWD cars, front and rear engined. I am decent at it, not great by any means. I do have one SCCA regional championship. I have no idea who Randy Pobst is without googling him. Rotating the car for the purposes of this discussion is in reference to a FWD car, you charge into the corner, lift off the throttle and turn, weight shifts forward, the car lifts the inside rear tire and the rear of the car slides sideways (car rotates), when the car is aimed where you want it, you get back on the throttle, weight shifts rearward, the rear stops sliding, and you accelerate out of the corner.
