"git reflog expire" (and "git gc") examines the reflog entries and discards old/stale ones using two criteria. The entries that are older than "reflogexpire" (defaults to 90 days) are unconditionally removed, and the entries that are older than "reflogexpireunreachable" (defaults to 30 days) are removed if the entry point at commits that are not reachable from the value of the ref. This is reasonable for local branches, remote tracking branches and tags. You (or other people) may have failed experiments that have been made and then later discarded by resetting the tip of the branch back, and setting the value of "reflogexpireunreachable" shorter than that of "reflogexpire" will prune the entries that describe these failed experiments earlier than the entries that describe the steps that led to the current history. It however doesn't make much sense for "HEAD" reflog. When you switch between branches, it is normal that the tip of the branch you were on is not an ancestor of the branch you have switched to. The moral equivalent of expiring failed experiments in per-branch reflog for "HEAD" reflog is to expire entries that talk about commits that cannot be reached from any ref.

GIT - the stupid content tracker

"git" can mean anything, depending on your mood.
- random three-letter combination that is pronounceable, and not
actually used by any common UNIX command. The fact that it is a
mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the
dictionary of slang.
- "global information tracker": you're in a good mood, and it actually
works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.
Git is an Open Source project covered by the GNU General Public License.
It was originally written by Linus Torvalds with help of a group of
hackers around the net. It is currently maintained by Junio C Hamano.
Please read the file INSTALL for installation instructions.
See Documentation/gittutorial.txt to get started, then see
Documentation/everyday.txt for a useful minimum set of commands, and
Documentation/git-commandname.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with "man gittutorial" or "git help tutorial", and the
documentation of each command with "man git-commandname" or "git help
commandname".
CVS users may also want to read Documentation/gitcvs-migration.txt
("man gitcvs-migration" or "git help cvs-migration" if git is
installed).
Many Git online resources are accessible from http://git-scm.com/
including full documentation and Git related tools.
The user discussion and development of Git take place on the Git
mailing list -- everyone is welcome to post bug reports, feature
requests, comments and patches to git@vger.kernel.org. To subscribe
to the list, send an email with just "subscribe git" in the body to
majordomo@vger.kernel.org. The mailing list archives are available at
http://marc.theaimsgroup.com/?l=git and other archival sites.
The messages titled "A note from the maintainer", "What's in
git.git (stable)" and "What's cooking in git.git (topics)" and
the discussion following them on the mailing list give a good
reference for project status, development direction and
remaining tasks.
