returned.

Just to provide some info on this:
Note that a link or button is normally the way of "leaving" an article. I'm not even certain that a web browser visually returns to the exact position to which the user scrolled if not returning after following a link. If it does, it should also fire the appropriate events for assistive technologies.
A screen reader can try to track this information, but I see two problems with this: 1. The state will be lost when the screen reader is restarted. This doesn't make sense if the browser is visually returning to the correct position. 2. If we track the information by URL, inaccuracy and unreliability can occur. Many pages can have the same URL with different post data. In addition, the page might have mutated by the time the user returns, in which case the remembered position will be incorrect. This is why I'd much prefer to try to get this information from the browser. The problem is that there seems to be alot of flakiness in this regard in browsers.
