I'd say it's slightly more overt. I mean he outright said that not only did he go Slayer, he was taking the whole Karaz Ankor with him. Yes, he probably meant it metaphorically - he didn't shave the Karaz Ankor's hair, nor his own - but still that's more than "I nearly went Slayer".
And considering that one of the kings standing before him is an actual slayer as well, that's not a statement to be made lightly.
