I read that conversation and most people said that you fold into the screen. I am 99% sure that's how you do it (that's how I did it on the DAT and I did well on the PA section). Think of the pattern as a dissected 3D shape that has been laid out like an animal skin. What you see is the outside of the shape, just like the fur of a bearskin rug...
If you try to do it the opposite way (folding towards you) I think you'd end up with the enantiomer in some cases which would be a wrong answer.
