Texas Aggie,
I think I was reading Chuck's post the same way you were.
But, after Back in the Saddle replied with (cut & paste) NFHS rule 4.42.5, I went back and read Chuck's post again. I believe he is saying the AP arrow should not be changed because AP throw-in was never complete.
See the other thread for complete explanation. (with all applicable rules in one place)
