How can you not work that way?

If you commit directly to master of your fork, then submit a pull request, you can't do anything else on master until your pull request is accepted. If you make further changes on master they will be included in the pull request, which you wouldn't want if they are unrelated changes. And once your pull request is merged, then what? GitHub will give you a nice "you can now delete your master branch because it's been merged" button...
