The transitions at 5:29, can also lead you to the outside clamp depending on which direction I turn to my side to attack. In the video I turn to attack inside, low side attack (I facing inside, towards his hips. I then attack his leg on the low side ((closest to the ground)). However is he pushes his leg towards the outside I can go to the outside clamp, attacking the ankle on the high side (my right hip) as his foot is on my him furthest from the floor. The location on the high side or low side of your hips is important as it changes up submission options, and transitions from those options.
