Actually, the post-TP dialogue and Asriel's speech at the beginning of the battle both use the overworld sprites.

And throughout the Genocide route, too, you start to lose control over Frisk. They walk towards many NPCs at the beginning of the battle without you pressing any button, while dialogue is happening, which never happens in any other route (Undyne stops the chase when you get a call from Papyrus during her netural/pacifist battle, for example.) The final blow to Sans is dealt without any player input, and Flowey is killed without input. Maybe during the Genocide route, Chara's getting enough power from Frisk to block your input?
