That's just a phrasing in speech and writing, and in your link it clarifies it means he was the "42nd president." How many actually sign their names/letters with the title President? That's a weird one. It would strongly imply they are still president.
Note, folks, that it says, "President Donald J. Trump."
Former presidents still refer to themselves as president.

Genuinely confused.
Okay, I believe you. Just never saw it before until now.
