Yasuo ultimate near enemy fountain

Typically when Yasuo ults an enemy under their turret he blinks to the side of the enemy opposite that turret. However if an enemy is on their own fountain,is knocked up, and Yasuo blinks to them during his ultimate, yasuo is placed on the side of the enemy closer to their fountain turret.
To Reproduce, simply ult an enemy that is standing on their own fountain. The detriment to this can occur when an enemy is on the edge of their fountain.
