I don't think he's talking about thin picks... he's talking about SOFT picks. There's a difference. A thin pick is still made of hard plastic... just thinner and more flexible... obviously good for strumming. No one uses soft picks fr lead work or most electrc guitar work... What this guy, I believe, is talking about is soft textured picks that emulate the texture of the flesh on your fingers... So to get the sound that you would get if you were finger picking. You notice when you finger pick with the flesh of your fingers you get a bassier tone... I think that's what he's talking about... not THIN picks... SOFT picks.
