That is not self landing. That's releasing to the safety. If your starting point is releasing to safety then you've used up all your options from the start. You have no fallback position. Even worse, you haven't learned anything. You've just dumped the kite and hoped it's going to work.
PS None of the videos in this thread show true strong winds. They're all light to moderate. In strong winds you have sand blasting your legs and boards flipping down the beach.
I used kites with IDS for 10 years. They worked fine, but occasionally the kite could roll over and fly upside down. It was easy enough to tweak a front line and turn the kite over to land it.
I am now using low-V kites with a single front flagging line. In the vast majority of cases working the upper front line parks the kite very neatly on its nose. The technique is easier and the success rate is much higher than that for IDS kites. Unfortunately, if it goes wrong the kite can flop around a bit more vigorously.
No matter what system you use and what technique you use there will be self landings with less than optimal results. An experienced kiter should have sufficient understanding to be able to cope with any behaviour of the kite during self launch and landing. It's not that hard.
It is unreasonable to expect that one specific technical implementation is going to result in zero incident kite behaviour. The very nature of kiting means that almost every session involves some sort of problem solving. The only 100 percent reliable method is to embrace that aspect and develop the skills to solve the problems when they occur.
For me, on a 40+ knot day the first decision is to choose a site that allows plenty of room for dealing with problems and mishaps. Rule 1 of all extreme sports is to have an escape route and to protect that escape route at all costs. For strong days I choose big wide beaches with plenty of run out room and plenty of room to release if the shit hits the fan. It never has, but it's better to have a plan than no plan at all.
