I'm not the first person to dissect this woman's form, but let me reiterate what others have already said. If you need to have a kip that big to perform a kipping pull up, then you're not strong enough to do a kipping pull up.
So what do you with this information? Take a video of yourself from a side view doing all four of these movements. Watch it carefully frame by frame. If you find that you've been doing these movements incorrectly, tell your ego to shut the f*ck up and go back to the basics. Decrease the weight and practice the movements slowly but correctly. You'll be better off down the road.
