backcourt or not?

That seems wrong.

So... by this case play if A1 releases the ball from the backcourt, it lands in the front court, and comes back to A1 in the backcourt, it's a violation...

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?)
