Mete's coffee is made using espresso from a good machine with a good grinder with good beans, the advice is for an espresso shot, or double, then steamed or hot milk. Some people like a strong coffee with a little milk, some like it full to the top with milk.
It was just a suggestion on how to get a coffee they way you might want it, strong, short or milky and long. Again the temp is all about preference, most Brits appear to want it thermo nuclear hot, but hey what do I care, the coffee at the Golden Moon Cafe was great.
