Kitty bleeds b4 the taunt. Extra DPS and TONS of extra threat. Wouldn't recommend berserk in that situation unless there's no important place to do it, though in a tank swap fight you'll usually want to hold berserk for kitty.
But anyway, he meant bears *cause* this problem too, meaning we tend to pull off people who taunt off us... which is a load of crap unless we've literally JUST hit mangle as they taunt. Cat form->cower is rarely unsafe, and from that point on you aren't doing 500% threat so if you outthreat any tank you can rightfully criticize them.
Lastly, I love that we single-tank madness and do Morchok on heroic. Add in that I'm unusually lucky on Warmaster devastate dodges (so threat is very high by the time any swap happens) and tank swaps are never an issue for us
