Over and Back - Please help on this hard to find rule

[Rusty Gilbert]

lorenj cited National Federation of High Schools basketball rule 4-35-3, which reads:

The location of an airborne player with reference to the three factors of Article 1 is the same as at the time such player was last in contact with the floor or an extension of the floor, such as a bleacher.

The Article 1 reference (4-35-1) reads:

The location of a player or nonplayer is determined by where the player is touching the floor as far as being:
a. Inbounds or out of bounds.
b. In the frontcourt or backcourt.
c. Outside (behind/beyond) or inside the three-point field-goal line.
