I don't see that Blake Cretney uses the resolute model. The resolute model says that for every possible set of ballots a candidate who is elected with certainty under this set of ballots is determined in advance. Blake writes e.g.: "Name: Reversal Symmetry Criterion. Definition: If alternative X wins (excluding ties), and all rankings on all ballots are reversed, then X must lose." If he really used the resolute model then the restriction "excluding ties" was superfluous because in the resolute model ties are not possible. I rather have the impression that when Blake says "If an alternative outside the clone set won for the old ballots, the same alternative must win for the new ballots" then he means: "For every possible random number X: If alternative A(X) outside the clone set won for the old ballots, alternative A(X) must win for the new ballots."
