No it doesn't. What does it do when you double-tap HN page on iPhone? Do that on an Android and see what happens. All it does on iOS is zoom till it removes the padding. On Android, it makes it a readable list, with correclty sized upvote icons, perfect reading size. It, in a way, instantly makes HN a mobile site. This is more than just zooming.
