Telling after a missed base

[Dukat]

I had a discussion with my brother about a game he had where after the next pitch and where the appeal was no longer applicable he mentioned to the defensive player that the runner missed the base (Funny thing is he said it happened again the next inning against the same player and she didn’t appeal that one either). He talks a lot to the players and coaches and says he does it anytime the situation arises but always waits and does it after the appeal is no longer available to the defensive player. I told him I always keep my mouth shut the whole time. What say you?
