OK, I've taken several pictures from the video.
1. He notes that the two middle cylinders are "fine". All show a burnish mark that appears to align with the skirt. Only the two outer cylinders he says he can feel scoring:

2. This is the piston from the above hole, he says the rings are stuck, but they clearly move when he's touching them in the video, so they are not seized/stuck, they do however, not appear to compress, which would indicate either improperly sized rings (they are butting) or something behind the rings preventing them from compressing. I will say again, they DID MOVE, so they are NOT seized. You can also see the polished section on the skirt that mirrors the burnish mark on the bore:

3. This is the piston from one of the inner holes, he says the rings are also seized, but this hole doesn't have scoring (but it has the burnish mark). These rings also clearly move when he touches them, so they are not seized/stuck. However, they appear how I'm used to seeing them when buggered up, deeper in the groove, basically flush with the piston:

I think there's more to this story/analysis.
We have some curious things here:
- Rings that clearly move, but don't compress. So, they aren't seized
- Burnish marks on all the bores and pistons
- Only the outermost holes have scoring, the two inner holes are fine
- Compression rings look clean and free
