I haven't seen your mandolinist in action; I would suspect instrument size, weight, and way of holding the instrument may be in play here. My own instruments do not move; I have never owned an instrument (lutes, guitars, viols) less than 62 cm. SL. (Small instruments in general give me the heebie-jeebies, can't seem to find them or hold on to them. Don't know how those virtuosi manage them) Also, I play sitting down, the lute anchored firmly between right thigh and right forearm. Don't use the right pinky for anything but secondary stability point- it's out, touches down when necessary, but very minimal contact, even for thumb-under. Somewhat more little finger contact during very fast passagi. No straps except for the archlute.
