It doesn't look like it is actually hi-jacking the back button, just a crappy ui. When you go to the site it shows a random screen and the expanded list so you can't actually see the random screen at the bottom. If you do click on a selection from the list it shows you the selected option without the expanded list. At this point the back button will take you to your last page (the first random selection) but without the expanded list so it looks different than it did the first time.
