It showed the ball release that comes with the Pintxo bar (which has no swivel), threaded through the Wichard in the little gap above the release arm. That solves the problem of losing your kite if the Wichard self releases.
In an emergency you do the normal push away of the red barrel to release to the safety leash.
If you want to ditch the kite then you have to release the Wichard THEN release the ball release.
It effectively makes the Wichard into a rotating harness hook or sort of chicken loop.
It's a little bit clunky. You have this extra ball hanging around doing nothing much, and when you hook in you have to attach two things. I guess that's no different having to put your chicken loop on the hook then attach your safety leash. It's certainly better than losing your kite. It does give you a reliable rotating attachment and a safety leash and it does away with the chicken loop.
I had shelved my Pintxo bar because the possibility of the Wichard self-releasing made me nervous. It had never self-released but I had other bars with better systems and bar end bungies and all the other good features. It is so much more relaxing to know that there is no chance of losing my kite, and to finish a session and simply wind the lines on the bar, pop on the bungies and go. I might try the Pintxo again with the additional safety ball and see how it goes. I really liked the compactness of the Pintxo, and the long travel on the depower.
