So listening to it right now, if you count this in double-time from the very beginning, when the drums come in (at like the 18 second mark) on One, the rest of the band comes together on the Four beat of that measure.
I would think that whether you have two guitars playing the intro, or even just one playing the whole thing, it would be essential that the whole intro is counted in very precise, fast time, else there's no way to find the beat.
