Nothing from Roger's execution proves that Doffy had dismissed his position as World Noble as far as I remember the chapter. The fact that he uses the same outfit as now and that he doesn't breathe from a globe are good statements, but not proves.

Also according to the translations I have read so far, we have no reason to believe that he threw away the position. He could be resigned by his own family or he could be kicked for a yet unknown reason.

Just for refreshment, I'm posting the most trustworhy of the translations: CCC's translation.
