There are (at least) two types of coasting:
1) In neutral (or EOC) you go a long distance and try to carry your speed as far as possible. This yields very high mileage (up to 380mpg in my car).
2) And the type you are talking about is when you want to slow down, and use the engine to slow down instead of (or in addition to) the brakes. This uses the fuel cutoff and you get "infinite" mileage, but only for the short(er) distances.
