Do you guys rate Bas Rutten's "self-taught" ground game?

I was interested when I heard Bas Rutten say his ground game was self-taught on Joe Rogan's podcast, so I checked online and managed to find an old instructional where he explains various subs and escapes. I was pretty impressed (like the hammer lock to arm bar especially) but I'm not really knowledgeable enough to know good technique when I see it, so I thought I'd post it up for evaluation:

It was filmed in 1996 during Bas's Pancrase days, so presumably his main influences were the Japanese catch guys and the Shamrocks.

(I'm sorry if this is some sort of copyright violation, by the way; the videos don't seem to be on sale anywhere anymore and when I checked Companies House register there was no sign of Nikko Toshogu Press so I think it might have been wrapped up. Figured in the circumstances that a link would be all right.)

From what I've seen in his books his grappling style seems heavily influenced by catch wrestling. The most unique aspect though was his striking while in bottom guard and I don't know where he learned or developed those attacks. He used those techniques very effectively in his title fight with Kevin Randleman and since then I have rarely seen people attack like that from the bottom of the guard. I think the last fight I saw like that was Musassi versus King Mo. Though Musassi lost, I was impressed with his ability to create distance with his guard in order to unload with hammer strikes, reminding me of Bas' book.
