In this design journal here they go into detail about the weight of peoples identities, so to speak. And the fact that a King being killed is going to lose a lot more of their total life span than some unknown peasant.
There is also another Discord post by Caspian from about a year ago I don't feel like diggin up, but the gist of it is that all of your identities combine to make a total of what happens as far as story points, death penalties, etc.
So if you do somehow pull off having 2 legendary identities, like say you were the King, and also Robin hood, Then you get story points based on both of them.
TLDR, Yes.
