Nope, terminology again.
"Another free throw is to follow" which I have to presume is language that you are paraphrasing from 6-7-2, means that due to the game action another FT attempt actually will occur after the current one is completed. It does not mean that an official mistakenly stated such.

You really need to stop putting your own personal meaning into these phrases and go with what the NFHS intends them to mean. You can deduce that from the play rulings and interpretations that the NFHS has issued in the past. Doing so will greatly help both your understanding and adminstration of the game.
