Most of the time an EC in my experience can reach a consensus on most matters. However, sometimes you just have to out-vote a dissenting view. Sometimes I am outvoted.
If a majority of the EC resolve to accept a particular quote, I would say that should be it. If one or two members of the EC preferred the other quote for some reason, then presumably they had the opportunity to put their case but failed to persuade a majority.
Sometimes you get people with odd views. Requiring unanimity could be a recipe for paralysis.
