This. Having thorough knowledge of the Nier and Drakengard games does not help explain what's going on (in usual Yoko Taro fashion), but mostly just gives you theories. It's either going to be spelled out to us within the next 2 weeks, or be left with a vague telling on how it happened. Though judging from how the previous 4 quests had us go through Copied Factory and Puppet's Bunker exploration twice, expect us to get a double dose (somehow) of Paradigm's Breach that will explain it.
