Don't feel bad, thorhammer! I spent about 2 years playing with everybody's take on what "it" means. This time, I wanted a reference to the make-up of each little group so I can watch the dynamic of how they interact.

When using that spread, you look at directions in column and row to get a feel for how the relationship might play out. If you click to enlarge the pic, look at the cards in the lower left corners. They are the clue to the direction of the squares:
Ace thru King (numbers)
Hearts->Clubs->Diamonds->Spades (suits)
But like I said- every author has their own framework for interpretation. I'm testing out what I can. It's my own little addiction. If it doesn't do anything for anyone else, that's cool too.
