Where did you read that same-document references only apply when

Scroll down to the algorithm in 5.2.2, and it backs up Tim and Sam, in
particular this:
if (R.path == "") then
T.path = Base.path;
Yes, so if the URI reference is empty, then the target path is the base
path, and so with embedded base URIs it is the embedded base URI.
To again quote the spec: "When a URI reference refers to a URI that is,
aside from its fragment component (if any), identical to the base URI
(Section 5.1), that reference is called a "same-document" reference."
This is all done after the algorithm has run, which specifically says
that the uri is identical to the base URI, so it is a same-document
reference.
It seems pretty clear to me that whoever wrote the same-document
references section simply wasn't thinking about embedded base URIs, and
thus it can be safely ignored. Your interpretation would contradict not
just the algorithm but practically the whole of the rest of the document.
Not at all. You have to remember that beging a same-document reference
sais nothing about what the URI actually is, but only that:
When a same-document reference is dereferenced for a retrieval
action, the target of that reference is defined to be within the same
entity (representation, document, or message) as the reference;
therefore, a dereference should not result in a new retrieval action.
