Shaco bug?

I don't have a video or anything, but while playing shaco on URF mode, i noticed a weird bug with his clone. When you command the clone to auto attack a structure (not sure if it is the same on champs) the clone seems to go to the side of the structure that your mouse is closest to, regardless of whether it was already attacking it. For example. shaclone is on the bottom side of the inhibitor and it is attacking it from the bottom side. Your mouse is closest to the top side of the inhibitor. You command shaclone to keep hitting the inhibitor, it will walk over to the top side and continue hitting it. Was pretty annoying when I played him but I'm not sure if it was a bug or not.
