Fix net or not?

[som44]

on Saturday during a JV Tournament team A shot and made the basket-the net got tied up in the basket after the shot went through--while B was taking the ball up court with no pressure from A at all i noticed the net- blew my whistle and fixed the net-gave ball back to B and the game
proceeded--I was being evaluated during this game--after the game all comments were very positive except that i was told the net should not have been fixed until there was a dead ball from a violation or OB. This means A may have gone back down and played at the basket with the net tied up in the basket- This just does not seem right
any comments?
