What does the keyword "title-in-title" mean?

My best guess is this keyword was originally intended to refer to this meaning of "title" in the first instance:

a descriptive or distinctive appellation, esp. one belonging to a person by right of rank, office, attainment, etc.: the title of Lord Mayor.

And this meaning of "title" in the second instance:

the distinguishing name of a book, poem, picture, piece of music, or the like.

I say that because many of the titles with that keyword include words like "queen," "king," "princess," "emperor," etc. Even "Dr." is included, and a doctorate can be an honorific similar to a title.

With that said, the keyword has been diluted to the point of meaninglessness, probably by other users who meant to add other keywords like "title-spoken-by-character" or "name-in-title" or something like that.

It was never a good keyword to begin with, given its vagueness. I would support full deletion and blocking of these two keywords:
