The CCA mechanics book does address blowing the whistle more than one time. I don't have my book with me, but I believe it states to blow the whistle more than once when something out of the ordinary happens. In my opinion, this doesn't totally expain the situations in which the multiple whistle is used. It is often used in traveling calls when a player is moving rapidly toward the basket. The official simply wants to emphasize that the play is dead to prevent further action from occurring. The most common situation is when players are physically tied up in a held ball or in a fouling situation. The official is then trying to prevent the player's actions from intensifying.
