This is a glitch that allows you to jump through wall pretty much wherever the wall is flat and there isn't an invisible wall behind. Doors doesn't work either as far as I can tell...
The glitch isn't really named yet but "Plating" and "serving" have come up as suggestions.
To do this yourself, just do exactly like in the video. There's no secret trick to it.
Other than that it's just some minor applications and fun scenes :)
Every shop's got a chest underneath the map that contains all of its shopkeepers items, have a look at the one under skyforge
