Infield fly rule after the fact

[prekowski]

Question for RKBUmp who says: Called or not it was an IFF situation and the umpire was correct in applying it after the fact and returning the runners put in jeopardy by the non call back on base.

Unless NCAA has changed their ruling, they do not allow the IFF to be called after the fact. The umpire must call it at the time of the play.

These two seem contradictory. On one hand it says it was right to make call after the fact but then says NCAA requires it to be called at the time of play and does not allow after the fact. Please clarify what is meant here.
