endwalker story confusion(SPOILERS)

[Mirhd]

I think they're referring to the reason why Emet and Hythlodaeus visited Elpis. The Hermes we meet in Elpis is a friend of the current Fandaniel, who has chosen him as a successor. They seem to have missed the part where Hermes does become Fandaniel.

Sure, but that's what I don't understand. The game was pretty clear on it, too, so it's really odd to come to that conclusion.
