I'm sympathetic to Philip's thesis;

  Technically, the text is not wrong, but I really wonder if for somebody
  new to IPv6 we should explain the address architecture this way.

But the unfortunate answer is; that is not the purpose of this document.
This document is a specification, not a document meant to teach anyone
about IPv6. In fact in the Introduction the document says this is a
specification, but maybe it would help if it also said what it isn't, that
is an Introduction to IPv6 and maybe even include a reference to the ISOC
IPv6 tutorial.

https://www.internetsociety.org/tutorials/exploring-ipv6/

Put another way, you don't learn to drive by reading the state traffic
ordinances, you read a drivers manual or guide, this document is much more
the state traffic ordinances in this analogy, than it is intended to be a
drivers manual or guide.

Thanks.
