Interesting situation in Varsity game last night.

I went along with some veteran officials to do a Boys JV game before the Varsity game last night. Nothing unusual about my game but in the Varsity the first half got very physical and the two official s must have called about 7-8 off ball fouls just in the first half. Home team playing triangle and 2 and face guarding players being manned up. So here is the situation during the game. A1 puts up a shot and returns to the floor(not airborne shooter), B1 knocks down A1 while trying to block him out, Trail calls pushing foul. At almost exactly the same time as the trail blows his whistle Lead blows his calling a pushing foul on A2 who pushed B2 under the basket on the rebound. They come together to talk about what they have and decide that the fouls occurred simultaneously so they call it a double foul and go with the AP arrow and Team A retains possession.

Just wondering if this is what everyone else would have done?
