Was intended as the answer of your last question and followed be some
explanation. Sorry if it was not clear enough.

As "physical" I understand something that exists and
has a body, an extend. An empty buffer I understand as of no extend, but
existing.
Thus the mark may exist whereas the region has no
extention. Thats possible with mark-active and
region-exist-p.
Therefor
(not (eq (region-beginning) (region-end)))
as proposed by Juri for Emacs looks necessary to be
sure.
