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?"
