This originally came from old movies and TV shows where two people are in a dangerous situation (usually hunting criminals or other enemies), and one of them is going to venture forward. The other person stays behind and watches for any danger coming from behind or other directions that the first person is unlikely to see. The one who stays behind typically has a weapon, to fend off any attackers.
