Most cars with horizontally-arranged dual-lamp headlights have the high beams toward the center and the low beams on the outside, and depending on how they're wired, either the high beams go on without the low beams, or all four lamps come on at the same time. So since the villains' car that Steve was tailing had just its high-beam (center) lamps on, it then would not have all four of its headlights on sometime later.
