I get most of that, just not how it ends up in a flat disc. as opposed to an array of discs or something similar. Is the idea that if you took the nebula, and measured across in 1 deg increments, the plane that had the largest percentage of largest objects is the highest probability of becoming the eventual plane? This seems like the sort of concept that could do with a nicely done animation to explain.
