It seems to take a highly reductionist pathway: reality/experience can be simulated -> simulation is computation -> computation is mathematics -> mathematical objects exist regardless of whether anybody has discovered them.
This implies that all conceivable universes (including the ones where a lot of really bad things happen on an eternal loop) are possessed of the exact same reality as ours.
