Charged Conference?

[5 sport ref]

At a varsity double-header last Saturday the first base coach, after her team made the third out, ran out to the pitcher's mound and smoothed the landing area. She then rubbed the dust of the ball then handed the ball and talked to the pitcher. I guess it is their supestition. Never saw it before and couldn't find any against it in the rule book. The defensive conference rule doensn't come into play because time wasn't called but I don't think the coach should be out there talking to her pitcher before the warm up pitches are started. Your thoughts?
