Only thing I see is there is no flux when you actually connect the two joint together. I was always taught there needs to be flux everytime you heat it, as it leaves an opportunity for oxidation when you reheat them, which can cause a cold joint. Reason their not good is someone who is inexperienced may not identify the cold joint and it feels snug at first, but vibration or temperature changes can break them. Since you did this as a how-to for the inexperienced, you might want to tell them to dab some flux on the joint before they connect the two together. little tin of it cost a dollar.
good idea to do this though, someone needed to.
Flux is sometimes in solder now, or mine is anyway.
