I think they all had a choice of when to do each type of dive. This 3.6 dive, most of them chose to finish with it, but Daley chose to do it at the start (it was the one he had to redo I think). He chose to end with a 3.3, but the others did their 3.3 earlier.
All did the same dives, just in a different order.
Having a different order can make you stand out a bit from the crowd. Having the easiest one last come with both positive and negative sides.
