This is a good question, and at least on ESPN the rulings on this were never fully explained. I still don't know whether the foul was ruled intentional or not. I agree the calling of intentional fouls is usually reserved for either really hard fouls or late-game fouls, and Andre's was neither, although if I understand the rules correctly it's actually within the ref's power to call an intentional foul whenever the player is not going for the ball.
