From what I've been told you are not supposed to touch the brake at all and let it coast to a stop. The reason for that is that both acceleration and braking require the use of friction which will take away from the friction needed for keeping control of the bike (similar in theory to taking a hard turn in a car).
Not sure if that is any bit true, but it does make some sense.
