automatic intentional foul

[Coach Bill]

An AAU game over the weekend (NFHS rules). There was about to be a breakaway at mid-court for a guy on the other team, and my guy reached in and committed a foul. He was going for the ball, but made sure that a foul was committed. I thought a good foul.

The ref ruled an intentional foul. I argued the call, and he said that since the guy was going to have a break-away, it's an automatic intentional foul. Even offered to show me in the rulebook after the game.

I think he's confusing an NBA rule and the clear path to the basket call. There's not really that rule in the NFHS rulebook, correct?
