backcourt or not?

But by the 3 points rule, if A1 is dribbling near the halfcourt line, is standing backcourt and releases the ball (to dribble) , it lands in the front court, and returns to A1's hands (as dribbles are apt to do) while A1 is still backcourt, you DON'T have a violation.

What's the difference (and what rule makes it different?)

Criteria for backcourt violation:

1. Team control (and player control established at some point if coming from a throw-in)
2. Ball achieves frontcourt status
3. Team in control is the last to touch the ball when it has a frontcourt status
4. Team in control is the first to touch after the ball gains a backcourt status

In your first situation, all four criteria are met. In your second, the ball doesn't achieve a frontcourt status per the 3 points rule for a dribbler.
