Mordekaiser's Ghost and Bard's Magical Journey

This is something small, but something I noticed in a game I had. Bard made a journey, and Morde continued through, however, the ghost had to walk around the wall. I don't know if this is intentional, but I believe if morde alt + right clicks Bard's Magical Journey, then the Ghost that he has currently active (as long as it's not dragon) should be able to pass through it. If you're reading this, thanks for that. x ??
