It isn't their own XD bit. They just couldn't help letting the lawyers rename it and put a trademark on it. It works exactly the same.

There is no Intel specific XD bit. It works 100% the same. It is identical. Intel just felt that they needed to rename everything because it would make things oh so much more clear.
