"Pre-heat" is done until your apparatus reaches the stable cooking temperature. The recipe writer doesn't know your pan size, room temperature, stove power, or anything like that, so they can't tell you the details.
"Low-medium" is just bad instructions. The recipe should be more detailed.
Anyway, what you are complaining about on your example is just jargon ignorance. You need to learn some stuff before you understand recipes. That's not really what makes programming hard. But it does make learning new things hard.
