out of the batters box

[bniu]

my understanding of this rule is this:

IF the ball never touches the batter: Then the ball can be ruled fair if it stops in the upper corners of the batter's box that lies in fair territory.

IF the ball touches the batter:

Case 1: Batter is not COMPLETELY outside of his batter's box, then it is a dead ball and an automatic strike except for the fact that the automatic strike CANNOT be Strike 3.

Case 2: Batter is completely outside of his batter's box, then he's out.

And no, the other batter's box does not count. Batter is only protected while inside the box that he's using.
