Haven't read the manual as I really don't need apt-listbugs for anything further than referance and pinning a pakage.I have only pinned one pakage in a year running sid.
I do understand your question and have been confused by apt-listbugs after pinning too....but,I just read carefully and went ahead,then ran dist-upgrade again.
