In The Sunlit Man, Sigzil mentions that Hoid often tries to disguise the purpose of his stories by saying they have no meaning, when he's clearly lying. I think that might be what's going on?
I'm working with very little evidence here, but this somewhat reminds me of Ati? In Secret History, he says that he was never an ordinary human, but a Vessel awaiting power. He then takes up the Shard of Ruin, which nearly destroys Scadrial while he's holding it.
