Pretty sure he's talking about this live action trailer the game put out before release:

Pretty sure it's not a literal representation of what actually happened in the lore. There's not even thirens or any non-humans in this trailer

>Hollows cannot spread where there is no organic matter to corrupt, which is why the Shiyu pillars were detonated to nuke the area surrounded Hollow Zero so there was nothing but lifeless rock, leaving nothing to corrupt and make Hollow Zero grow any larger
>Yet there's giant hollows on the Moon, and half of it seems to have been consumed already.

What could this possibly mean?
