From his video I can't tell if the OB is frozen or not. If the OB is Not frozen I'd say he hit the, 'Cushion first.' Obviously, if frozen, 'Ball first.'
I can't believe it but this video I created was in 2013. I know 100% the OB is frozen to the cushion in my video, and "I" play all 3 positions, 'Ball first.'
BTW, there were several members here at the time that doubted I made the shots, 'Ball first' when I posted this video many years ago.
Around 2014 or 15 I was in Philly at Pete Fusco's 'The Spot' pool room to put on a 3C clinic. I demonstrated how I make a 3C shot by 'back cutting' the 2nd ball and go across the table to score a point. Our own, Mitch Brown AKA (MKBTank) was present in the room. There was a GC table next to the 3C table, and I demonstrated the shots in this video for Mitch and fellow Pool players.
Note: The speed and stroke are different for each position, the tempo and timing are the same.
