Because git lied to you. When it says "you are up-to-date with origin/master" it did not actually check that it is up to date with the code on the origin. This is one reason why Git is inhumane. It's reasonable that it didn't check with the remote repo, but its misleading use of the word "origin" does not help new users.

But 'origin' is just the name of the remote repository, not something hardwired into git, right? (Maybe this response is undercut by the fact that it is the default name.)
