I assume you're talking about the solo section. I'm playing a downstroke on the lower part of the chord, followed by a ghost downstroke (lower volume), then getting the E, B, and G strings coming back down. It is not really that important what the notes are on the downstroke, it's more just the feel for the lower part of the chord.

I'm playing an open E before I go to the B7.

Hope this helps, let me know how it's going!
