Why do we increment csp and cst?

I understood the part of initialization of the loop re-initialization and the work part but I am not able to understand the incrementation of csp and cst . In CRX pattern 4 .

The incrementation of csp and cst is done to obtain the required pattern.
Try to dry run the code on some sample test cases. You’ll understand it completely.
Go through all videos of patterns and then try to code yourself.
