A valid point, but the original question really is: should
you use mark up an acronym/abbreviation with its expanded
Version if the expanded version is already adjacent to it.

It would be my view that no, that's superfluous.

Keep in mind that Internet Explorer does not support ABBR...

Exactly. As the web is not a purely linear medium, and that
pages may not necessarily be read in full (e.g. a screen reader
user getting an overview of headings, then jumping to the relevant
heading and reading from there), it's difficult to pin down the
"first occurrence" of an abbreviation/acronym. I'd say it comes
down to consistency: decide which acronyms/abbreviations need to
be marked up as such (e.g. on a page aimed at politics students
relating to USA's foreign policy, should every single occurrence
of USA be marked up, or would it be reasonable to expect - depending
on target audience, of course - that it's a familiar acronym that
does not require marking up) and then be consistent throughout
the rest of the page/site.
