The word "who" and the implication of location is not enough to hang an infringement.
It also means the same thing, and almost rhymes. "Who's Here" and "Who's Near" probably shouldn't both exist doing about the same thing - it would cause confusion. With "Who's Near Me", I think it's no longer a worry (in terms of what the law should be doing - I'm not a lawyer, so I can't speak to what it is doing until we see what happens in court, if it gets there).
