Inadvertent Whistle?

I mistakenly signal the block preliminary, then immediately realize the error. I go to the table and report the charge. All this is okay, unless there was a double whistle and my partner gave the charge signal all the way, in which case we must report a double foul?

I would like to know the intent and purpose of this rule.

I have no problem going with a charge in this situation since the "calling" official's intent was to call a charge and he gave an incorrect signal.

In the Blarge scenario you are always arguing about, there is no mistaken signal given. One officials sees a charge, the other sees a block. In NCAA-W by rule you go with PCA. In NFHS, NBA, and NCAA-M you go with a double foul.
