POI and Referee Magazine case play

[Scrapper1]

The rule on ball location seems pretty clear. Just like for a person who is airborne. It is where it was until gets where it's going.

If the long pass is still airborne, then the ensuing throw-in would be from the spot closest to where the pass originated. If the pass bounced on the floor before the whistle, then the ensuing throw-in would be from the spot closest to where it bounced.
