WotLK Rogue is now using a typhoon?

Hi, before the moment when I shot the video, there were a couple of cases where within 1 minute, 2-3 times, this rogue threw me back (like a typhoon on a moonkin), that is, the cooldown was about 10-15 seconds. What is the name of this item for knocking back the enemy? or is this a bug of this BG or what is it?
