The video shows the shake in combination with the Split Stroke (UCN:S1fRH1-sDI.sUI123.sDI34) and a Triplet Stroke (UCN: S2fRH0-SDI.SDT.SUI) in the end. The sound of the Shake and the Triplet Stroke is very similar. According to RH the shake is a swift flick of the wrist rather than a conscious movement. The Triplet seems to be more consciously accessible is might therefor be chosen when slowing down in the end.
