According to Matthew O'Neill (http://www.rleague.com/article.php?id=19486), "Back in 1996 the ARL had the perfect Finals setup, which has since been adopted by the AFL with great success. The ARL used a similar model in 1995 but was better in 1996 due to the swapover pool to avoid teams playing each other twice during the Finals, which could have been the case in 1995 except both Brisbane and Cronulla went out the back door."
This is what actually happened in 1995 rather than the system.
