text: If the spell that's countered was the back face of a modal double-faced card, no card in the player's library will have the same name as that spell because those cards all use only their front-face characteristics while in the library; however, if the first card the player exiles that has a different name than the spell is a modal double-faced card, they may cast either face, even if the back face has the same name as the countered spell.
