Accordion stroke?

I was watching a kid who had posted some practice videos of himself, and he had some elbow movement in his stroke--oddly, it was up/forward. The overall action is similar to a pendulum stroke, where the movement of the cue is limited by the closing of the arm. However, instead of his hand swinging through an arc, it moves straight back to front, because his arm closes like an accordion (causing the elbow displacement).

I have never noticed anyone else do this, but maybe I have not watched enough people. As instructors, is this actually common, and would you not recommend that style, purely based on elbow movement?

"Piston stroke" - common among snooker players - I don't recommend it, but others do. Its purpose is to deliver the cue tip in a horizontal line (for tip/ball accuracy) - but a "pendulum stroke" (fixed elbow) can also deliver the tip accurately if you set up correctly.

That makes sense...I always equated "piston" with an elbow-drop stroke, because it was not "pendulum". But, it seems obvious that's what it is, and I see the error of my ways!

Thanks, Patrick.
 
Eva Mataya Lawrence had the most obvious version of this I've ever seen, probably because she was so lanky and often played sleeveless. As PJ mentioned, it is a piston stroke. But her elbow dipped on the backswing and raised on the forward stroke much more than just about anyone else's.
