Lucian Relentless Pursuit and Red Buff

I don't know if this is considered a bug, but when I use Relentless Pursuit to dash through certain points of the wall at red buff, I can't use it to get out. What I mean is that if I try to take the exact path out that I came in from it won't let me. I know there are certain points in the wall that simply cannot be dashed through in the first place, but this is not that situation.
