The position of A-1 in the air indeed plays a crucial role in determining the legality of a 3-point shot based on the last contact with the floor. According to basketball rules, for a shot to be considered a three-pointer, the player must release the ball while their feet are behind the three-point line. When a player is airborne, what matters is where their last point of contact with the floor was prior to the shot. If their last contact was behind the line, the shot is credited as a 3-point attempt, regardless of where they release the ball while in the air.

This understanding reinforces the importance of tracking a player's positioning relative to the floor for determining shot legality, rather than just focusing on the release of the ball itself or their position relative to the line during the shot.
