I don't think it's a matter of milliseconds at low speeds like this. He'd have to be faster with the opposite lock if the tires break traction quicker, but that car takes approx. two and a half years to rotate - Autobahn-cruiser that it is - during which time he has every oppurtunity to correct the steering. Doesn't matter much how the tires grip if the wheels are pointed in the right direction when they do. If slow speeds like this would require fast reaction times then it would be far beyond human capabilities to save an F1 car from sliding at high speed.
