Yes, your analysis is correct.

Not quite: browse-url--non-html-file-url-p is non-nil only for file://
URLs which target a non-HTML file.  In that case, browse-url-emacs will
find the file in the respective mode, e.g., image-mode for images.  That
doesn't seem awfully wrong to me.  It prefers opening files in emacs
rather than external programs, that's for sure.

But if you prefer having them opened by the preferred windows program,
add

  (setq browse-url-handlers
        '((browse-url--non-html-file-url-p
           . browse-url-default-windows-browser)))

to your init file.

If you feel that the default value is totally wrong, please file a bug
report so that this can be discussed.

Bye,
