Again, Equestria Girls influence.

It's implied that the native Earth humans use nicknames and that those aren't their REAL names, it's just a coincidence thast their nicknames match the birth names of the human counterparts.

The only exception to this is Human Trixie, who goes by her real name. Possibly Principal Celestia and Vice Principal Lunas as well, since it's more likely than those are their real last names.
