Fair, but don't conflate this implementation with the idea (e.g. the line separating the next page and previous page). You're "alternate solution" is great; did you try it on this page? Works fine with page down. One use for the two torn half-pages is that you can still see the preceding text for reference. I think that's the main reason for it. Otherwise, use page down or the arrows.
