If the SP allocates users the equivalent of a /48 divided up as multiple >/48s with semantic meaning to each of the assigned prefixes, then the user's got a /48, and the SP's got their semantic bits.

It's that a /48 is assumed, and because it is assumed, there are definitely bits available for semantic prefix assignment. I still don't understand. What the above sentences seem to be saying is that "there are bits available for semantic prefix assignment because RIRs assume /48 but users don't actually get /48". Is that your point? If so, I don't see how you can also state that there are enough bits to both give every user a /48 and to use semantic prefix bits.
