Class and Level Geekery VIII (spoilers ahoy!)

[Winter]

Eugene had Epic level scrying and had been following the order basically since its inception. He is an expert on their powers and abilities at the time he makes this statement, and Roy does not disagree.

Also Eugene did want to make his son feel bad about losing this and as the factual leader of the Order, it does not really matter if he was higher than them, he'd still be the leader of the entire thing.

So no, I do not think it's reliable enough to consider this statement by Eugene to be some actual proof.
