I'd guess that it does try to open it in an external application, but,
after it can't figure out what that should be, it falls back to Emacs.
You could step through the call to org-open-file to get a better
understanding for what it is trying.

I don't know how Ubunutu assigns default applications, but org-open-file
looks at mailcap assignments by default on GNU/Linux systems (see
org-file-apps-defaults-gnu).  You can also specify an
extension-application mapping using the org-file-apps variable.
