Not exactly, more like... If you really pick the wrong choices.
Such as ****** the guy off, then choose an option that lets your character get pissed instead of letting the taunts go over their head...
It would be like the point system in previous games (for example in the Brecilian Forest in DAO, if your score on one of the quests goes below X, stuff happens... or in the Landsmeet, if you fail to convince enough people... blah blah blah...)
Let me show an example - If you have -3 points, good bye. If you have +3 points, you stab the hell out of the other guy. If you have anywhere in between, the duel goes on until situation X ends it, either by another character making an entrace, or a draw, or whatever you wish.
