This is likely true.

The test looks like

(unwind-protect
        (org-test-with-temp-text
	    (format "#+begin_src octave :results file graphics :file %s
sombrero;
#+end_src"
		    file)
          (org-babel-execute-src-block)
          (should (search-forward (format "[[file:%s]]" file) nil nil))
          (should (file-readable-p file))
          (should-not (buffer-live-p (get-buffer "*Org-Babel Error Output*"))))
      ;; clean-up
      (delete-file file)
      (when (get-buffer "*Org-Babel Error Output*")
        (kill-buffer "*Org-Babel Error Output*")))

So, unwind fallback forms are likely executed.

Thanks for the pointer!

I think this bug report can then be closed.
