It's more that the same event happening in the two worlds precludes the existence of DAA in one world but not in the other, so either it happened in a different way or it had a different outcome. Whichever is true, the lack of DAA to erode human order seems like something that would affect how effective or unopposed his return would be. The cryptic stuff about the planet's cornerstone and the principle taking hold should at least pertain to it.
