That depends. I use 5 pages but each page has a clear purpose. From left to right:
Games, social, organisation (calendar + clock), Internet (bookmarks + search widget), media (music, videos, YouTube and so on). The only app I use on a regular basis that could fit on multiple screens is YouTube, and I can easily remember the position of one app. Swiping the wrong way does not cone into that.
Your point only applies if you fill the 5 pages with apps as they're installed, iPhone style.
You could easily create folders and fit all of those on Screen 1 on iOS. 1 click to open any folder.
As I've said a number of times, the usage patterns are too different. If you're using your screens as folders, then maybe you want the left-swipe functionality. If your screens contain every app you install, then that might not make so much sense.
I'm not saying Android is wrong to have left/right screens, merely that the behavior would generally be wrong for iOS.
