After reading that, I think the system is somewhat comparable to Read Dead Redemption's Honor and Fame system. Honor (like Morality in ME) increased and decreased towards good and bad ends of the spectrum depending on the nature of your decisions, while Fame (like Reputation) only increased. So Morality determines who your Shepard is, and Reputation determines how well the galaxy knows of your actions.
