Good point, everyone is not as into guitar solos as we are, I guess. So yes, I can see the point of it in the context of the full show (although I wish he could have stuck with other parts of the songs and not exactly at the point someone's soloing). Especially on Powerslave, as that is just THE solo and such a big solo for Dave.
The same when watching bootleg footage, how annoying isn't that, when the person filming has his camera at for instance Bruce running around when Adrian or Dave or whoever is playing a solo. FOr me, the focus must always be on the soloist. But then again, you do have a point, not everybody is as (enormously) occupied with guitar solos as (for instance) me.
