The URL identifies the repository. When you do a "pull", you obtain the
_set_ of all revisions that exist on the remote but don't exist in your
local tree (remember that in a distributed context every repository has
a complete history).

You can then fast-forward the state of your working directory to any of
those revisions (similar to "cvs update -r {foo}" but without a server
trip). This local update is astonishingly faster than a network update;
git in particular can update an entire source tree to a different
revision id so quickly that new users often wonder "did it just core
dump?"
