Both of those. It is explicitly clear from the Final Hours app that there is no deeper meaning to the end. It's just half-assed writing coupled with a purposeful intent to make things vague. They wanted something "memorable" that caused "lots of speculation". Well they sure got that, although I suspect not quite in the manner they intended.
