After a true pacifist, Flowey speak to someone (refering with "you") that have the power to reset everything and he said at the end of his dialogue: See you later... ., so Flowey think that this person is Chara. But, the player (the one that have the capacity to reset anything) is not Chara because Chara speak to someone else (someone that have caused the world to be destroyed by Chara) at the end of the Genocide Route.

So the player is IN the game (like the SAVE, the RESET and other option normally out of the game), it's another entity, not Chara or Frisk.

And, Asriel, like every monsters, can make mistakes (he speak to someone that he think is not Chara, and, after, to the same person that he think is Chara).
