I don't think they claim that the universe cares where they put their cutoff. They just say that in order to give a meaning to probability, we have to take the limit as some cutoff approaches infinity. Because certain types of absurd events have probabilities that are bounded away from zero no matter what cutoff you choose, these absurd events must therefore have non-zero probability. This seems to me like a reductio of the idea of using cutoffs to define probability, but their claim is that the value is meaningful, since it's a limit, and doesn't depend on any particular arbitrary cutoff.
