Yeah, attached to his right hand.
Resolution isn't great, but here, look:
That is not a 'two up two down' legspinners grip.
I can't see f-all in that pic other than his level of pronation.
2 up 2 down is a bad descriptor. An orthodox wrist spinners grip features three finger-points of contact all roughly 90 degrees apart, which is basically what this chap does. Finger spinners is the same except the ring finger is optional and the first 2 fingers might spread out a little more.
