I don’t think that’s the obvious takeaway. The specific chord voicings are complicated, sure, but the complexity he’s talking about are the key changes and unexpected tonal choices. You can’t remove those without fundamentally changing the feeling of the song.
When I was learning the guitar, I frequently would skip passing chords and simplify voicings I didn’t know how to play. As a result, my covers were pretty boring and lacking the impact of the originals. That’s fine for beginners, but a pro musician is going to take pride in either faithfully recreating a cover or intentionally putting their own stylistic spin on it, not just skipping over stuff that’s hard.
