This is incorrect and quite misleading. Intentional fouls need not be "intentional," and not all "intended" fouls count as intentional fouls.

Example 1: Team A is behind by 2 with 20 seconds left, B is bringing the ball in. A1 fouls B1 on purpose, making a basketball play, in order to stop the clock. This foul is "intentional" in the sense that the foul was deliberately committed as a foul, but it is not an intentional foul.

Example 2: A1 is throwing in, and B1 flails his arms, accidentally reaching across the line and contacting A1. This is an intentional foul, even though B1 did not mean to make contact.

Intent to foul is neither necessary nor sufficient for a foul to be an intentional foul. The term 'intentional foul' is somewhat misleading that way, since intent to foul is not a criterion at all. See 4-19-3.
