I can do this move now! You can do it with turning or without.
You really need to slide the centre point around your arm a lot to get it in a good position for the second matrix and you'll need to do this again for any subsequent matrix propellers. What's easier is to the let the staff roll away from your shoulder, before the matrix starts. More so than for a normal matrix, and do the matrix closer to your elbow. It's much easier to get the second matrix clean doing it this way, and doesn't require so much slide.
NO VOICE OVER. :(
