We (and they) are in a rock-and-a-hard-place situation. It's good that they're working from their own stashed copy instead of hitting us live, because I doubt our servers could handle their users' load. But of course on the other hand it's supremely annoying that they're working from their own stashed copy, because (as you note and I emphatically agree) our lovely instantaneous wiki-quick edit-save-test loop is broken.
Why can't we have the best of both worlds? They get the co-ordinates from the database dumps, but when a user clicks on the globe icon they get the live page. We should be able to handle the load if our servers are only hit when a user actually tries to read the page.
