I ulted 3 times in a teamfight as nautilus

In my last game I was playing support nautilus. Not long ago they made nautilus's ult not only knock up the target but also people on the way. and during the teamfight I realized that every time the enemy tahm kench devour me before my ult hits the enemy target, my ult would get cancelled, but the cd is refunded and the enemy before the target I selected still got knocked up, so in that teamfight I basically used 3 yasuo tornado and rekted the enemy cuz they all get chain knocked up.

not sure if this was intended or not.
