Why RCA cables can use only one cable for video, but need 2 for stereo audio (L+R)?

Seems like a 640×480 colour video should be more complex than a stereo signal audio.

It doesn’t have anything to do with the amount of data. The left and right audio channels are split at the source, so they each have a separate wire. The entire video signal goes down one line. When that single video channel isn’t enough (it’s really more for a cleaner picture than because of the amount of data), you need a component cable, which splits out the brightness and color in to their own separate lines.
