About Pix

Whilst playing Lulu, I've noticed that if I flash over a wall, or if I use Help Pix! (her E) on someone and they move to the other side of a wall, pix flies all the way around the wall as opposed to just flying over it. I don't know if it's supposed to be like this, but it's kinda awkward to watch that happen instead of him just flying over the wall.
