I think the rule is also aimed at not allowing the players to make the court bigger than the in-bounds area. Suppose a player wants to run the baseline but cannot because there is a defender blocking their path. Fine, go out of bounds to get around the defender, come back in on the other side, receive the ball and lay it in. Does the defender have to go out of bounds to stay in front of you? One can see all kinds of strategies that could be build using the going out of bounds "wormhole". This rule mitigates that greatly by requiring at least one intervening pass before such a player is "legal" again.
