I think they might be referring to the "Braveheart" in the center screen, however it's my conclusion that P1 is Delita Heiral, and they've made it so that you don't see your own character's name floating over their head (since you know who you are), and the "Braveheart" is a temporary title, like the other party members' "Dragonslayer", "Materia Hunter", etc.
