Having worked games involving this coach I am sure he asked if it was a legal position or thing to do. He usually does know the rules, but wants to get a warm fuzzy that his idea is not going to bite him later on.
This being said, no matter what the umpire has to say, this was handled the wrong way, where could the F4 been? Behind the F2 and the umpire?
This is a strange situation and most of us do not want to affect the game in the way this umpire did.
