That makes sense - though most of the time if a method call only makes sense give a particular state, it's generally set to be protected. You can still call it with the wrong state from within the same class, but I can't honestly think of a case of that happening in my work.. You generally are familiar with the workings of the class you are currently touching. If you aren't able to do that practically, then that generally means your class is simply too large.
