I think what EY is saying is that, rQM entails MWI, and only an extra layer of epistemological interpretation denies
the reality to the worlds. ie, he thinks MWI says “QM implies many worlds” whereas rQM says “QM implies many worlds, but we should just ignore that”. (One man’s ontological minimalism is another man’s epistemological maximism).
But that’s all based on a sequence of misunderstanings. rQM doesn’t allow observers to make contradictory observations AND there is no observer-indepenent world-state in rQM, so there are no multiple world-states in rQM.

So true.
