I have observed that some female doctors (from any academic field; h.c. or regular) like to put a "Dr." prefix in front of their names, in their social media profiles. I guess some women do this to signal "I am open to interactions here, even with random people from the internet, but preferably on a professional level. I am an expert in something myself." - in order to receive less toxic content, less rudeness, on social media. Perhaps he was thinking about doing something like this himself.
