Sounds like standard G-D-A-E to me.
It’s very interesting his rotational movement when he needs to skip strings or change string on a different stroke, I watch him all the time in his live streams and this seems to be his main technique for that. He often is doing this wrist rotation to achieve escape. It’s a very relaxed motion that he does intuitively, I think this only comes with a lot of practice once you find what works.
