Yeah, I get that point, pal. But I'm mainly aiming to the part of the games that wold be more exciting and make the anime will audience. If I get too analyticous, I could also say that Ash still has to meet Lorelei from Kanto's Elite 4; as apparently they erased his encounter on the Orange Islands for no reason. (Was it for the stupidity about Jynx?).
They referenced him meeting Lorelei in Johto.
