Touching up on foul ball

[Bobbyg]

Pony Baseball. Mustang Divsion. 9-10 year olds.

Runners on 2nd and 3rd. The batter fouls a ball off.
Runner on 2nd base does not touch up.
Another pitch is thrown which is not touched by the batter.
No runners advance.
The opposing manager appeals the runner not touching up.
The ump calls the runner out.

I believe this is a bad call on two levels

1. An appeal must be made when the ball is put back in play but before another pitch is thrown.

2. Touching up is not required as long as the runner is in close
proximity to his bag and is not advancing

Your thoughts would be appreciated

Thanks
