Even if the box level is too high to make a jump back, You can make a 2-ways direction connection there. Why? If the most top WP on the bigger box is connected only with one (next WP) and it is not a goal nor a camp WP, so it will never be used in any path generated by bot code while the bot is walking on the map, so the bot shouldn't try to jump there back. Only if You would put there (at the top) a camp or goal WP or that WP would be connected with yet another WP, there would be a risk the bot would try to jump back and get stuck there. I hope that trick is clarifing a bit the situation.
