Yes, one of them said something like "go on and say those eight words then", referring to the slogan that Blitzchung then said while wearing the mask, and both were generally sounding amused.

Production for the event could have told them -- or simply canceled the interview any time after realizing -- and didn't. So the casters had to improvise, it's not fair to blame them as if they shared intent, rather than just wanting to keep a surprising live situation light-hearted and on the rails.
