I would have thought that before, but if he is riding smoothly and fast I now understand he's doing what I'm doing right behind him. This has not always been my riding style, but is consistently now. The key is very easy/gradually on the front brake and, once off, very easy on the throttle to maintain speed in the corner before hammering back on. Another benefit I see is that if you need to emergency brake in the turn (never good), you are already on the brake so there's no lag time with applying the brake and them heating up to grab. Plus, you're less likely to snatch the lever.
