In similar behavior, one of the votes against the community bylaws that seem to have resulted resulted in the expulsions was "If the Board majority group insists on proceeding with this misguided and premature motion, I vote NO". Those in favor decided that the vote was conditional and not valid, because "this motion is neither misguided nor premature". They then proceeded to tell others complaining about the decision that they were violating community standards in doing so.
As far as I can tell, the invalidated vote made no difference to the outcome; it is difficult for me see a legitimate motivation for the interpretation of the vote.
It's like they're setting themselves up for a "no true Scotsman" argument. Anybody who disagrees with their decisions isn't a "true believer" in open source.
