It doesn't seem to be. I have put together a ECM. I have two CSS files,
representing a “base” style and an optional “override” style. I have two
versions of an org test file that differ only in the first 2 lines of the
file. One “works” (loads both style sheets and displays the text as
described in the document), one does not.

This is a minimal ECM. In my actual setup I have the equivalent of the base
CSS file in a file named ~org-options.txt~ that I include into every single
Org file I ever create via ~#+SETUPFILE"~. I load my override CSS on a
per-document basis in the document header below the ~#+SETUPFILE:~
directive.

* Hello this H1 Should display in red
The exporter should include file ~test-org-export-base-style.css~ from the first
~#+HTML_HEAD_EXTRA:~. In fact if this test file includes only that line, the  exporter
works correctly and the ~H1~ displays in red.

This text should display in blue because the second style sheet includes a definition for
HTML paragraphs. The block quote blow should display nicely formatted on the right from
the second style sheet also.

* Notes
** Works
If I combine the ~html_head_extra~ lines like below, I get the desired result.

#+begin_example
#+HTML_HEAD_EXTRA: <link rel="stylesheet" type="text/css" href="test-org-export-base-style.css" /> <link rel="stylesheet" type="text/css" href="test-org-export-override-style.css" />
#+end_example
** Doesn't Work
If I have the ~html_head_extra~ on two lines like below, I get just a ~<link
rel="stylesheet" type="text/css" href="test-org-export-base-style.css">~ line in the
output. I don't get an include for the ~test-org-export-override-style.css~ style sheet
and therefore the HTML text display in default black and the ~<blockquote>~ does not
display neatly on the right.
#+begin_example
#+HTML_HEAD_EXTRA: <link rel="stylesheet" type="text/css" href="test-org-export-base-style.css" />
#+HTML_HEAD_EXTRA: <link rel="stylesheet" type="text/css" href="test-org-export-override-style.css" />
