They
look like they're aligning their left feet *very* carefully with something on the floor just beforehand, so I'm guessing that they've got some sort of hinged rod concealed in their left trouser legs that engages with a hook or similar and locks in place when they lower themselves to the correct angle. I've seen yogis who use a similar gimmick to 'levitate'.
