I'll bet that helps interrupt vortex creation. On wings (planes or race cars), side plates effectively extend the wingspan, but I think they are also used to minimize vortex's. In this case, they probably also help the air flowing around the side pull in and re-attach, kinda like the air flowing over the roof going down to the trunk.
I wonder how much benefit one can get from a stepped down boat tail versus a regular boat tail. Better visibility out the rear window, methinks.
