Many moons ago my dad did teach me, i had to fit one recently so went to the shop trying to remember the rhyme he taught me that was similar to yours. Got there feeling confident i knew what i was doing, picked one up and realized it had a cardboard overlay with a diagram showing exactly how to fit the cables.
I think i could have done it without but tbh it looked like all of the plugs had those diagrams so only a muppet couldn't do it.
