The head writer of a Doctor Who series generally writes more than one episode. I can name six Stephen Moffat episodes in Series 5 off the top of my head. While I'm not suggesting our going that far, it does seem logical that the head writer would at least be given two episodes with which to introduce and finish a story arc.
