Communication to get call straight

[just another ref]

Last night, boys varsity, last minute of a close game. Visitors make a steal and wind up with a 2 on none. B1 lays it up and as ball is on the rim A1 comes flying in and smacks the board. (the classic we're gonna lose now but look how high I can jump thing) Partner was lead, kinda right beside the play, he whistles and emphatically signals basket good. I blew my whistle to get his attention and called a quick huddle. "What did you call?" "Goaltending." "He didn't touch the ball." "Ball had already hit the board." "If he didn't touch the ball, it can't be goaltending." Well, it's a tech, anyway." He shrugged. I thought, uh-oh, he thinks, goaltending, bucket good, technical, close enough. I said, "Technical is what it is, or nothing. It's your call." He went over and huddled with home coach. I saw him gesture in my direction, so I think a part of his explanation was "cuz he said so." Home coach yelled across at me, "Does the basket count?" I shook my head no. Visiting coach meanwhile had a pained expression,
"What....what is the deal?" Partner simply said, "Technical foul." Home coach added, "You're getting the best of the deal." The ironic thing is that I think both coaches were happier with the wrong call than the right call. It turned out to be a non-issue. B missed both t shots, then inbounded, got fouled, and made both.

My question is, when I told partner it can't be goaltending, if he had refused to change the call, there would have been nothing further for me to do, right?

I was already mentally practicing saying, with a straight face, "He called goaltending, coach."
