I don't think we can say that Autonomy did anything substantial to help Odium with D&D from that WoB. "In any way" could range from splintering Devotion herself to saying, "Hey, Odium, did you know there's a planet with two Shards on it?" Given how hesitant that WoB sounds, there's at least some amount of reaching involved.
Also, Honor and Cultivation were together for thousands of years. They were romantically involved. I don't think they would have been distant from each other...inasmuch as distance means anything to Shards, for all of that time.
