It does to you, since you are used to it. To me it makes sense this way. The 100 coefficient is just used to make the numbers "nicer", nothing else.
Anyway, l/100 km is not about fuel efficiency, it is about fuel consumption. It says that if you plan to go Y km, you need to have Y liters of fuel.
Saying one way makes sense and the other not is like saying that period makes more sense then frequency.
