No, it doesn't. If you look at the prices you linked, you can see that the full cost of X-Plane 10 is factored into the bundle deal.Comes with free X-Plane 10.
I think flight sim is good for when you're working on your IFR rating and beyond. I also used it to prepare for interviews that had simulator portions to get better awareness of the instrument layout. Good luck and enjoy every step of the way with your training!I played a lot of flight sim growing up and it didn't really affect my flight training in any appreciable way, positive or negative. The thing that home flight sims like that don't do for you is reinforce procedures which I would argue are just as important as understanding the basics of powered flight (I'm not a CFI, so my analysis could be way off).
Play flight sim for fun. Don't expect it to be any kind of meaningful tool for your real world training.
