I work in an industry with a lot of self-important life-coach-style assholes.  Frequently, these guys will share some semi-generic inspirational quote image, and if you look at who it is attributed to, it's them.

I got into a disagreement with someone not in that space for doing the same thing the other day, and I pointed out that, since their name is already on their social media account, there's no need to then attribute the quote to themselves within the image, comparing it to an author of a book adding a "~ John Doe" within the text of the book, even though his name is already on the book itself.

Am I wrong for thinking that's superfluous and silly?  I'm sure part of my distaste for it is the kind of people I usually see doing it, but is there some grounds for it being prudent to do?
