The problem with that is that the way you say it makes it sound as if it was just a recording. But tbh the way Minato talked it did not feel like a pre-recorded message at all. It very much seemed like Minato was summoned from the DeathGod into Naruto.
But as I stated before anything at this point is pure speculation. There just is no evidence in the Manga to proove or disproove any of it.
