Galio's Bugged Taunt

Just has a game with a Galio mid, we had a jungle fight near dragon and as I grabbed a thresh lantern he popped his ult, this made me run all the way from where scuttle spawns back to where he was around the death brush. I was CLEARLY out of his ult more than a screen away and it still taunted me back in his team and caused them to easily win the teamfight and then the game (we were getting steamrolled anyways).
