"Leaving Early" (pitch) to pull up socks

[Dakota]

14U rec level fastpitch. ASA rules.

Runner gets on base, and is of the type that sets up waiting on the pitch with her "back" leg on the bag and the "front" leg forward down the baseline toward the next base. She has a bad habit of once she has taken this position, she will pick up her foot (off the bag) to adjust her socks, or her slider, or whatever. Clearly, she is not taking her lead-off step. She is just adjusting her uniform, etc. I don't call it, but tell the coach between innings that her player #99 needs to be more aware of herself while on the bases and not lose contact with the bag, etc.

Long-winded way to the question.

In a game that mattered (higher level ball, tournament, etc.), would any of you NOT call this?
