*CMIIAW, but I see it, the postulates tell us the possible results of measurements. They don't assert that every possible measurement will be realized. So I see an additional assumption in the MWI.

I was trying to explain that the Multiverse of String Theory is manifestly *different* from the Many Worlds of the MWI.
