Well if the theory is bullshit then surely it does not actually help anyone understand religion? So the Gods are speaking to people in the Iliad because it was actually one half of the brain speaking to the other. But the Odyssey allegedly is composed after the watershed moment, but Gods are still speaking to people. So the theory does not actually explain anything about religion.
The theory can "rationally" explain how Aphrodite speaks to Paris, but it does not explain how she teleports him from the battlefield to his chamber. So you still have to accept either supernatural events or that the story contains fictional elements. In which case the gods are much easier explained than through this theory, which have no other evidence.
And the narrative style of the Iliad (describing events and actions but not thought processes and introspection) is known throughout history.
