You are right to point out there is potential for confusion, because different VCSes model the practice of branching and merging in so many different ways: - a single text field in each commit, as in Mercurial - a list of "sticky" keywords attached to each commit, as in CVS - special revision numbers, as in CVS - special directory names, as in Subversion - pointers to the tip of a line of history, as in Git Each model has its strengths and weaknesses in terms of supporting different operations one might to perform on a branch: - creating a branch - advancing a branch - studying the history of development on a single branch - fetching and pushing - renaming a branch - deleting - comparing the history of two branches - merging and deleting the now-merged-in branch - merging and not deleting the now-merged-in branch - "context switch" from working on one branch to another In particular, you are right to emphasize that in git's model, "what was on the foo branch at 12:00pm on Saturday" is just not a well defined question. The foo branch tip might have been at commit A on my machine, commit B on a server we share, and commit C on your machine, so Git doesn't even bother --- branch refs are pointers into history rather than participating in the history themselves. Instead, we can content ourselves with the answers to questions like "what was in the foo branch at 12pm on Saturday on the server used as a rendezvous point", by logging in and examining the reflog on the server. A nice side-benefit is that branch refs are considered to be _private_ unless they are pushed or mentioned in a commit message. So there is no pressure to come up with good names for them.
