As I understand it, “goodness” is being used in a somewhat confusing way there, referring to not only outcomes in the world and the actions which lead to those outcomes, but also preferences or personality traits which lead to those actions. In other words, there is a set of mental qualities which results in preferable outcomes (good) and a set which does not (evil); God has all of the former qualities and none of the latter, therefore similarity to God can be taken as evidence of goodness and vice-versa.
The main practical difference from Friendly AI is that God is presumed to already exist.
