these not even a wall trick like long wall or parkour wall or jump extended wall this is just a wall that randomly place and expose your self in to every direction XD
The guy is obviously still working on perfecting the walls. Also not everyone speaks the language jut because its the most used. He is trying to show the walls thats more than enough.
