Why do people twist CPC's?

Graham The Spark: 
 

The latest video from “Doctor Electric” on YouTube has really annoyed me(titled "Best ZS Ever)!

What is it with these YouTube “Sparks” that they think they can just start up a channel and think they're god?

On this video Doctor Electric shows viewers how to twist the CPC's to get a better ZS!! UNBELIEVEABLE!!!

Using the drill to twist C.P.C.s together tightly looks like a good way to damage them. I may just twist together the ends of C.P.C.s for a cm or so to provide a good reliable connection in a socket terminal, but I would never use a drill and twist the whole length. Also, if somebody wants to test for ring continuity at a socket untwisting the C.P.C. is very difficult.

I don't like C.P.C.s bring just pushed singly into socket earth terminals as they may not be reliably gripped. One may be only loosely gripped.
