Most likely they are still pointed to by the reflog. By default,
git-gc will expire the reflog after 90 days, and these reference will
then actually be pruned.
That's really usefull to allow you to recover your work with "git
checkout HEAD@{whatever}" even after a mistake and a git-gc, but you
pay it in terms of disk-space. One alternative is to expire your
reflog explicitely.
