Bug: Death Sentence bringing champions over walls. [gameplay]

In two separate games I was able to pull an opposing champion over a wall using Thresh's Q. First time occurred over mid lane's top brush. I was hidden in brush and hooked Swain, who slid through the wall into the brush with me. The next game I hooked a Yorick through the wall across from dragon pit entering red side's jungle. Both times the other champion and myself were standing near the wall being passed through.

To reproduce have Thresh stand in brush or out of enemy sight standing near a wall, land a hook, and the champion will be pulled through the wall. I did not hit Q again and we did not exchange places.
