That's not addressed by the proposed text.

The second clause addresses scalability.  If people need to parse,
dereference, or otherwise provide *additional* disambiguating
information to have any reasonable confidence that their identical URIs
identify the same "thing", the system won't scale.

That's not precluded by the proposed text.  The proposed text says
nothing at all about how you find out *what* a particular URI
identifies.  It simply says that a single URI reliably identifies the
*same* thing, no matter what context it's used in.

(In other words, it's ignoring the issue of *how* you find out what a
URI identifies.)
