Yes, I was referring to pictures in general. The audio describes the need to get the left arm, clubshaft and especially right forearm their impact fix alignment at impact. This would be done through the pressure points. Again, I believe his focus was on how the pressure points allow the club head to be properly released. From the looks, and again, we're past follow through, I think it's a strong single grip, but with vertical (maybe angled) hinging.
Hope this helps - it is hard to tell from that position, but I've watched these videos many times (as everyone has) and I don't remember any discussion of grip beyond strong single.
