When is a conference charged?

[TwoBits]

I would say this is definitley a bit of OOO, but our OOO is also wrong with his interpretation.

FED 3-1-2: If a pitcher is replaced while his team is on defense, the substitute pitcher shall pitch to the batter then at bat or any substitute for that batter until such batter is put out or reaches base or until a third out is made. To ensure that the requirements of this article be fulfilled, the umpire will deny any coach-defensive player conference that will violate the rule.

A conference should not have been charged. Using the correct interpretation, our OOO should have disallowed the coach back onto the field during warmups.
