If you're treating git as a centralized VCS, that is, there is only a singular upstream, perhaps, say, GitHub.com, then that makes sense. That, however, is not the only way to use the tool (though GitHub.com obviously has their own opinions on whether that should be the case or not), but the upstream repository that you're pulling from certainly it's an important distinction if you're using the tool beyond how GitHub.com wants you to.
