Looking at the website, it seems this software might be helpful for a beginner, one who has never put pen to paper, so to speak. If you've never tried your hand at writing a novel at all, and don't know what works for you yet, then the software probably couldn't hurt as long as you're aware of its limitations.
It reminds me of those writing workbooks, like The Novelist' Notebook. You can see one way to build and organize a story's groundwork. Taken along with many other perspectives (of course, reading other novels being the most important), it may be helpful. Obviously, the software isn't meant to be a magical tool that will write for you, but if you have the money, there are worse things to throw $60 at, I suppose.
