A possible second theory that I have is air flow. With two windows open he could reduce the smoke in the room. There are any number of simple reasons that avoid the necessity of two shooters.

I don't believe there were two shooters. If investigators had any reason to actually believe that, there would probably be a nationwide manhunt by now.

I'm only speculating that Paddock may have expected to have someone else there, but that person never followed through.

The smoke clearing idea makes sense, but these windows were broken in two separate rooms, with only one doorway separating them. If that were my reasoning, I would have broken a window on the opposite side of the same room, not along the same side of the building in a separate room.

My arm chair comment:

Dude had airplanes so he knew how wind works at different altitudes. Wind is different on the third floor than it is on the 32nd. If he broke two windows in the same room, there may have been too much wind which would cause the bullets to fly back in. Thus he breaks the window in a different room so that the wind would have a diffused pathway out.
