Question?

[just another ref]

The whole problem here is whether the terms "call" and "signal" are meant to be interchangeable in this case.

A1 drives on B1, who is planted and waiting. I am positive that A1 is going to run him over, but at the last possible split second he crosses over and changes direction. B1 is fooled, just as I was, and attempts to recover but sticks his chest out and turns an almost certain PC foul into an obvious blocking foul. I see all this in my mind as I blow the whistle, but my hand didn't get the memo, and it grabs the back of my head. oops As I report the blocking foul, coach B says, "Hey, you signaled PC!" "Yep, I anticipated. My bad."

Same situation as above, but my partner also had the call and made the correct signal from the start.

Is a signal, which I knew was wrong by the time I made it, binding in either of the above cases? I don't see how it can be.
