Contratulatory contact w/FTer???

[Freddy]

Please confirm or correct my reading of NFHS 4-47-2 that if even one teammate of a FTer goes to "give five" to his teammate at the line, that the delay it causes is a violation and would receive a warning for first time, T for subsequent times.

I understand the cautionary counsel as to when and when not to call it. I only want clarification as to the rule.
