second intentional

[rsl]

Team A is down by two, about twenty seconds left. B1 has an uncontested layup from behind and A1 wraps him up from behind. Easy intentional foul call.
B1 makes both shots.

During the ensuing inbound, A2 pushes B2 off ball. It is minor frustration push - A2 is not really savvy enough realize he is also stopping the clock. But, Team A benefits from the foul and the contact is off ball, so I call an another intentional.

I'm thinking I kicked this one. The second call should have been common foul based on intent. But whether there was intent or not, the foul stopped the clock and gave A a big advantage.

Is this an intentional?
