front or back court status?

[Hawks Coach]

One foot in the backcourt is backcourt. The line is like the OOB line, that is, when a player is on or over it, the player has backcourt status. The only way to establish front court status is to have both feet front court.

The jumping rule then works just like the OOB situation you describe correctly. When you leave the ground, you retain the same status you had before you left the ground. In this case, the player has backcourt status (one foot in backcourt) and retains that status until landing with both feet in front court.
