out of bounds vs 4 hit call

[MomofA]

Team A-23, Team B-24. Player on Team A hits the ball into block, the ball goes out of bounds, stat person from Team A catches the ball and rolls it to line judge. Down ref calls line judge to ask him if he saw if ball went out of bounds. Players on Team B and Head Coach on Team B is talking to up ref and signaling 4 hits repeatedly. Team A gets ready to serve and up ref blows the whistle, match point, Team B wins. When coach asked what happened the down ref said up ref called 4 hits even though he clearly saw the ball from a better angle. What was the proper way to handle this situation? The original call was touch/out, Team A's point. This was the point that determined who moved on to regional competition.
