I wonder if it sorts by popularity ahead of relevance (maybe after meeting some minimum threshold for relevance). In another post I've commented about the surprising high quality of the results.
@realdonaldtrump has huge reach on Twitter, as well as a distinctive style, so maybe there is no one who posts in a similar style (TBH I'd expect most to be parody accounts) who has achieved sufficient popularity to compete.

This could be used to de-anonymize people on twitter.
Edit: So I did a test for an old twitter account I don't have access to anymore. I was able to find it using my comments with few tries.
