The "Odu" being cast seems to be the myth's depiction of Orunmila's simultaneous reversion on prior principles and his illumination of Obatala's own Intellect. Or perhaps the speaking is the latter and the casting of Odu is the former. Either way, some sort of intellectual relationship is happening.

I think this is one of those moments where it seems like the very structure of the Intelligible might be non-Proclean, or perhaps just where my reliance on Hellenic categories might fail, because although I see Obatala as Demiurge here, I can't seem to place Orunmila.
