All I can say is that when I use the link you last gave (with FireFox, or the Android browser on my tablet), and select 'Play' from the menu, I get a different start position as what was initially shown. And when I then go back to the previous page, and press Play again, I get yet another setup. And it gets shuffled in the way that was specified. So the preset appears to be OK.
Perhaps others could try to see if they have the same experience.
