Tip #1 should have been "Learn the #$%!@ fretboard so you know what the #$&! you're playing." Is there anything more fundamental to bass than knowing the fretboard? How many guitarists do you know that don't know where the notes are? Just patterns or memorized licks. We're like "Grab that C up there" and they're all "derp, derp, derp."
Anyway, I've never watched any of his stuff but I guess I'll have to so I can form an opinion.
This is TalkBass. We don't need no stinkin' FACTS to form an opinion!!
I played with two guitarists over the years that didn't know ANY of the notes on their guitars. I've told this story elsewhere so I'll be brief.
1) The first guy could play Keith Richards like nobody's business. I didn't know he didn't know the notes on his guitar until he brought a song in and I said, "What key is it in?" He looked puzzled, looked at his guitar, looked at me, looked at his guitar, then strummed a chord and said, "This key."
2) The second guy nailed ZZ Top, absolutely copped the tone and vibe, along with the right notes. We were playing the Allman's Good Clean Fun and I wrote out the notes for one of the parts, literally like "A, C, D, F# ..." We come to the next rehearsal and he can't play the lick and I said, "#$# *&#$ it, I even wrote this #$$% out for you!!!" He looks at me and says, "I don't know any of the notes on my guitar."
I don't play with people like that any more, it's too exhausting trying to communicate with them.
