Correctable Error Question

Saw a missed correctable error situation yesterday. I was in the stands watching the JV game before my Varsity. Visiting team at 6 fouls, home team has the ball. Shot goes up, hits the rim, comes down and there is a rebounding foul against the visitors. The ref reports, goes back and puts the ball in play. Me and my partners are like "WTF?" The table never signals 1 and 1 and the home team isn't protesting either. Well I (perhaps unwisely) decide to go down to the table and see what's up. There is a timeout and I go to the official scorer and ask "shouldn't that foul have been 1 and 1?" He responds "no, it was an offensive foul." I go back and tell my partners we gotta watch out for this table now. I was thinking he might have only been the scorer for the JV game but nope, when I went to do my R responsibilities for the Varsity game there he was. Thankfully he didn't recognize me from 30 minutes earlier and we had no problems during the game.

I didn't know the JV guys so I didn't mention it to them.
