It simply says: " When the solution is mesh independent, you are free to use any types of mesh". (4). I think, a country kid from US visiting city friends in London would make comment that drivers in London love to show off the driving skill, that they put the gear in reverse all the time when driving in the city.

Make sure that the parts can work in both directions, like a car.
