I'm not sure how your first point applies here. If I get a patent for copy-paste using gestures, does my patent apply to using a mouse or any future copy-paste methods? Maybe, maybe not, it doesn't actually matter here because those methods don't exist yet so talking about them is irrelevant as I tried to point out. If you read the whole of my comment you'd see that I went as far as to suggest the patent itself is most likely invalid.
