Just Checking

[Chess Ref]

Had a sitch last night I want to check up on.

#1. I am T in front of Home Bench. Buzzer for end of 2nd Qtr goes off. Home coach turns to me and just starts screaming "Over the back" . He says this several times and I try talking gently and politely but he won't stop. So I T him. We shot the throws then went into the locker room. After the break The V had the arrow anyway so they started play. Should they ,the V ,have kept the arrow after the throw-in that started the 2nd half ?
