NFHS courtsey runner intepretation

[PABlue]

Okay I might be WAY out there on this one but we here in PA received this interpretation from NFHS on courtesy running. You tell me if you think this is wrong.

Situation: Catcher bats during a inning and reaches base safely, he then is replaced by a legal courtesy runner. The team bats around in the same inning again reaching the original catchers place in the order.

The question is can the catcher come up to bat again in that same inning?

According to NFHS the answer is NO. Here is there exact reasoning.

"Because once the CR replaced the catcher, the catcher can not reenter for the CR in (that half-inning) Pg. 93 CR# 3.
Neither could the CR bat in that position due to the fact the CR can not be used in the same half-inning. Therefore, the team would have to use a pinch hitter until the half-inning is over".

This is one I'm really ready to hear what other umpires have to say.
