What is the difference between a 6 wheel swerve and a 4 wheel swerve?

What is a 6wd doing that a swerve can't (aside from possibly climb easier, which wasn't the reason posted in the document...)?

If the wheels are not steered independently, (which I don't remember them being on 1625's 2010 robot) then it allows the robot to rotate about its center much easier, with far less turning scrub than a 4WD crab setup. It also gets you to Einstein and turns lots of heads and costs a small fortune to make.
