Hm. I believe this is so that when the second user's session ends, the first user, when his X session is made the current one, will be required to log in. I agree that it would be beneficial to prevent the screensaver from actually using up CPU unless it's the currently visible one, but I think the fix for this is likely to be far from trivial.
