All of those are tricks that he has made up. You should either make up your own, or if you really really want to learn those specific ones for whatever reason, you just have to watch them until you understand them. That’s all you can really do.
Yeah, nobody can do them except for Tyler and John. They wouldn’t be world champions if everyone can do their tricks. That would be considered copying of someones tricks, and that’s not cool. Just go make up your own tricks, and I’m sure nobody will copy off of you because it’s your own trick, and style.
This is why people yoyo: it’s a creative outlet through the tricks you make up. Yeah it’s cool to be inspired by the concepts and movements that they are showcasing here, but when was the last time you saw, let’s say… Yuuki doing Augie’s tricks in a freestyle? You probably won’t ever use these tricks on stage, and if you did, you probably wouldn’t be scored very high. Concepts and ideas presented in a trick is a completely different story. If you really want to learn the tricks though, you could always just watch these videos over and over again until you understand (recomended), download a slow-motion software(if absolutely needed), or simply ask the pros at the next contest you see them at.
At around 0:23 in this video, Augie does the exact same trick as the first video you posted (or, at the least, something very similar), except it’s a little easier to see what’s going on. It may help you.
