Is the iframe important to the functioning?
definately...
It looks to me like it is using the behaviour of the browser history (back
and forward) for the iframe.
(you hit "back" and the iframe goes to the previous url that was loaded in
it
- in this case http://www.tjkdesign.com/articles/keeping_state/zurl.html
plus a query string which changes)
