Babe Ruth - Visit to pitcher

[ozzy6900]

I am a little confused here. My son umpired a Babe Ruth game last weekend. The home coach is a FED umpire and a good egg. However, when he asked for time to visit his pitcher, he would not cross the foul line. His pitcher & catcher had the meeting at the line like LL used to be. My son (UIC) instructed them to have the meeting on the mound as stipulated in the BR manual & OBR. The coach stated that he does not cross the line because in his opinion, he does not belong there "between the lines belongs to the players". The discussion was quiet (my son informed me of the conversation later) and he allowed the meeting to continue.

Now I am a rules guy so in my opinion, he has to meet on the mound or we don't know when the meeting is officially over (OBR 8.06 - BR also). What is the opinion of my brothers out there?
