The very first report I submitted (
http://comments.gmane.org/gmane.emacs.orgmode/53824 ) showed the historic behavior correct (the two tags defined in org-tag-alist show up in the fast tag completion window). The "bug" was after shifting to free tag selection mode, the tags defined in org-tag-alist are not available for completion.
The behavior that Matt Lundin reported was/is a side effect of the fix (implementation). I think that the idea of the fix is valid, e.g. the free tag entry should autocomplete tags defined in org-tag-alist to match the behavior of the fast tag completion window.

Hi Mike,
I just reverted the commits I pushed for fixing this "issue".

I cannot do any better than to quote Matt Lundin on this:
"Historically, only tags explicitly defined in org-tag-alist or via an
in-buffer heading show up in the fast tag completion window."
So, let's stick to the current behavior.
Thanks for your patience!
