I’m not trying to be dense, but where does the article claim that “twofers” are fallacies? Can you quote the relevant passage?
EDIT: FWIW, I asked Vipul and he denies that the article makes such a claim. He also notes that the argument would be fallacious if its proponent argued that both of the empirical facts obtain (rather than arguing that one of the two must obtain).

It doesn’t say that explicitly, but he doesn’t sound very convinced that the argument is valid either; but hey, word of God.
