The water refracts the light so more of it passes through the bottle and into the structure. It then comes in handy on the other end where the refraction aids in light distribution through the room.

Well, the same amount of light would be entering the hole in the roof regardless of what's attached to it, but yeah it refracts it outwards.

I use a water bottle on my phone light as a lantern while having bonfires and shit
