Answer: There are more than 2. They are positioned similarly and look similar to The Bride's. So, Tarantino is saying The Bride isn't the only passenger with a kill list. This is where Tarantino reminds us that this is an allegory with The Bride representing all good people seeking revenge against the evil people who wronged them. A common theme in Tarantino films.
