Stunt kite flyer here. Flying (both powered and unpowered) is about managing the mechanical energy in the kite/aircraft. If you have kinetic or potential energy available, you can always trade one for the other. If you have neither, you've almost landed.
This kite will always be doing quite significant movement, so the "apparent wind" on the airfoil surfaces should keep it moving even when the wind is dying down. Additionally, you can reel in the tether to give a little bit of movement to the kite. Typical kites can be flown by walking backwards at a normal walking speed (4-5 m/s or less).
This looks like a very controllable kite, I'm sure their control programs can land it in pretty adverse conditions safely.
