In Perforce, which is more or less what Google is using, you can branch any directory within the repo. (You would never branch the whole repo; that makes no sense.) So if you wanted to construct a directory with one version of one subdirectory, and a different version of another subdirectory, that's quite straightforward.

Google branches google for releases. Otherwise, you would end up with version skew across dependencies, which would be a mess.
