Inaccurate meme - the white and red RCAs in composite typically don't actually carry the left and right channels - usually, the white one is L+R, meaning both the left and right channels combined into one, and the red one is L-R, the difference between the right and left channels.
This is done so that a mono television, which will only have a yellow and white port, will still be able to hear both audio channels, as opposed to having to completely miss out on one of them
That makes so much sense! I never understood it, and it became irrelevant before I worked it out.
It's so funny, I had the same reaction! Never quite understood it, just switched plugs until it worked. Then it got phased out and... decades later a meme brings light to my confusing childhood!
