Can it Defrag your boot disk?

The versions of this software on the app store don't defrag your main disk that you boot from. I was wondering if this (more expensive) one does?

    No version of Drive Genius will defrag your system disk if you run the application from the same system disk you are attempting to defrag. You must boot your Mac from the Drive Genius DVD and run the software from there or boot from an external or secondary bootable drive that has the Drive Genius software on it. All versions (at least recently) support that method.
