If you look at the image posted by LightCube containing the lighting diagram, it appears that no PocketWizards were involved: http://images.indiegogo.com/medias/990821/pictures/full/20130817183338-BalloonSetup.jpg?1376789622

So, I don't see how the flash duration of 1/500, which they explicitly mention in the diagram, would cover the frame evenly in their scenario.

It's called "tail sync." A 1/500 flash duration means the light is emitted for 1/500th of a second. As long as the SS is equal to or less than the flash duration you will get a relatively even exposure. That typically means a 1/500 T.1 time (not the typically quoted T.5 time).
