The problem is that the link below to the explanation is named
which is of course strange because this is Cemetery, not Province.
Many cards (including Cemetery) are affected by the same setting and it was named after one card that will always be present in a kingdom.
The "Province-specific options" describe the list of cards that the game will not ask you about to discard from Exile if a copy is gained, if the autoplay setting is "Keep bad cards in exile". It's Copper, Curse, the Ruins and almost all "pure" Victory cards (those with no other type).
