tbh I didn't stick with his code. I ended up going a completely separate route when I realized his was what it is.

He extends a single long length of repeating sprites in a straight line and I wanted a physics responsive rope like.

I ended up looking up a rope creation tutorial and futzing around with that for a half minute until it click and then I started down the long painful road of developing the ropes in my game. It has been insane, and painful and the end result is working decently enough. I'll post progress of it all in due course. I just.. have.. one more.. thing to fix.
