If the IC is right, how are they causing conflict in the Signposts?

I’m not sure how much of one I even have. My instincts don’t lead me right or else I wouldn’t have so many questions. I’m trying to focus on one thing-- the Signposts, but I get stuck on how they are supposed to progress. I can get why S1 is potential and S2 makes things worse but I don’t understand how you can “multiply” S1 and S2 to get S3 unless that’s just a creative way of saying “things get even worse.” Then S4 is where the solution comes in.

PRCO was mentioned in the videos when working with Signposts, so that’s why I bring it up.

I wish there were explicit instructions written down somewhere on how to write them, such as “ask yourself what problem is caused by S1. How does S2 make the problems of S1 worse?” etc.
