This has to be a comedy routine. And it's a brilliant one. So good I actually transcribed part of it:
"You just move your fingers
as fast as you can
around the notes of box 1 or box 2 or whatever.
And you just pick faster, you know,
it's not about being clean or anything
you try and pick...
...
faster.
Hopefully around the notes that your fretting hand happens to be on.
But you don't want to get bogged down in like
synchronization and stuff like that, because
that's the whole point of it being a secret.
You don't need to learn a whole lot to do it."
He seems genuinely concerned that if you were to accidentally develop good technique, you'd miss out on the fun of using a gimmick.
