Not necessarily. Depends on point of impact and angle of impact.
Presuming the Pelosi's could afford insulated glass, the first blow is unlikely to break both panes. Tempered glass, required for doors, is quite strong. It would therefore take at least two blows. Glass from the first blow would fall on the same side as the impact. The second blow would still likely make the glass fall on both sides since the impact wouldn't carry much beyond the area it strikes.
We had someone throw a baseball-sized rock through our sliding patio door in the middle of the night (the ongoing wonders of Brandon’s America). There were big piles of glass both inside and outside. A lot of the glass didn’t completely shatter with the initial impact, but kept dropping in shards over time after it happened, throwing glass in both directions. So, I wouldn’t read too much, one way or the other, into there being glass outside Pelosi’s door.
