That's as I suspected, since the rest of his technique was so purposeful and accurate. I'd still like to know about the double-block thing, though.
JT,
Most practitioners see this as a double block just as you have
This technique is widely used in many of the hyung in TSD.
1) Get a partner.
2) Challenge each other in a front stance with your right legs in the rear.
3) Have your partner execute a front kick to your chest. Using what you see as the preparation for the double block, (with your left hand) deflect the incoming kick to upward and to your right side above the outside of your bicep.
4) Capture his leg at the ankle with the inside of your right arm, trapping the ankle between your bicep and radial bone.
5) Simultaneously, use the left hand to strike (Hadan Mahk Kee) into his inner thigh or his hip socket.
Be careful as you execute this application to not damage his knee. If you perform this application with full speed and expansion of your arms and chest, you can cause his knee to bend sideways; damaging the medial region of the knee joint.
If you execute this application and slow down at the end of the movement, at the point that your left hand makes contact with his inner thigh or hip socket, drop into a deeper stance and this becomes a safe and easy take-down technique and makes for a good demonstration.
Let us know how it works for you
