I think you should stick to your own style, i mean everyone has a little difference in his line and driving style, its not always the best to copy others.
About the hotlap replays, many WR setups are heavily based on oversteering, because it allows higher cornering speeds. But this makes the car nervous and requires a lot of rapid correction movements. So many hotlaps are done with very low steering-wheel-lock and FF settings, this could be the reason for the quick movements you saw there.
