Looking closer at /usr/share/doc/dpkg-dev/triggers.txt.gz:
Packages in `config-failed' or worse are never considered to have
lists of pending triggers. A package whose postinst is being run
can however acquire pending triggers during that run (ie, a package
can trigger itself).
The docs seem to support triggering oneself is valid and it works not
just for pakages in `config-failed' state.
