Yes so there's 3 panels. The left side, Referencing Rules, are the rules that use the rule in focus. The right side, Referenced Rules, are the rules that the rule in focus is using. So for your example, Property B would be on the right side, Referenced Rules, because the data transform is using that. I like to read it as: "The left side uses the right side" which can be said for all 3 panels.
