Yes. Being ejected from the game means you must leave the floor area and not participate in the game as it is being played. There is no rule stating that a disqualified coach cannot address his team at halftime. Chances are the Stanford coach (2008 NCAA March Madness) was watching the game on TV in the locker room and knew what was going on in the game and had his halftime instructions prepared when the team entered the locker room.
