Twitter on my desktop has a notification that there are new tweets, and I haven't seen if FB automatically loads more content on the top or follows a similar approach. The point isn't that sites need to be static for the life cycle of a page reload, it's that the site shouldn't trigger a browser-level reload on an unrelated user action such as scrolling to the top of the page. It's confusing, and should be considered an anti-pattern as others here have said.
