Gul'dan demonic circle tp + Garrosh into the fray

Hi, I would like to report a funny bug (except for Gul’dan at that moment):

being in front on the ennemy’s base I threw Gul’dan behind me with Garrosh by using into the fray to save him but he teleported at the same time to his demonic circle that was in our fountain.
As a result what was my surprise to see him teleporting to the fountain then immediately flying across the map to the point I had targeted thus throwing him that way to the ennemies for a certain death with the little hp he had left before teleporting.
