seems to be the same pattern on the high strings with a slight variation and alternating root notes

Mostly at that video. I still seem to have trouble doing these sorta.. chord changes?

Also I'm wanting to learn how to really create this kinda sounds? I'm guessing they're just chords notes play seperatly rather than at once

It is as you say.
Learn the chords, learn to do the chord changes fast, then learn to pick out the strings individually, practice makes perfect :-)

Line 6 Spider IV (Don't judge me, I was young and stupid)
Stagg SW203N
Yamaha APX500
idk how new you are to guitar or whatever; but when I was learning to change chords when i started, it really helped to learn what fingers were already in place for the next chord in the sequence so you just have fingers shooting around instead of your whole hand coming completely off to change shapes
