The paths are written so that they contain a single intersect point and the path indices describes which intersect(s) belong(s) to which two lines in the form {lineindexA;lineindexB} and paths with nothing in them don't touch.

Using path{A;B}, from the original list of curves that were input, lineA would be found at index(A) and lineB would be found at index(B)
I think sets>cross ref is the key component you need to cross reference one group of lines against another.

thanks you very much.

Check this as well.
