I am not sure why you think I was trying to describe browser behavior.
You need certain things in order to apply the text in question, "When
a same-document reference is dereferenced for a retrieval action"; in
particular, in order to have a same-document reference you need a re-
ference and a base reference as "same-document reference" is defined
in terms of the two, and you need some cause for a retrieval action.
You also need a specification that defines you have these things. So,
this is just the basic setup I am assuming when reading the text.

If you dereference a reference for retrieval and also have a base re-
ference, then you can decide whether the reference is a same-document
reference, and if it is, then you have already retrieved the resource
and should not retrieve it again. The HTML specification would have to
say that something triggers dereferencing for retrieval and it would
have to say what the reference is and what the base is (if anything).

I think it is fair to look at this in isolation, so, yes, pretty much.
