I presume the theory is based around you never trying to get into BIG BIG while riding. Actually if you go with Sheldon Brown's method it shouldn't be possible to go BIG BIG coz the chain will be too tight to get there.
This is one of the reason's I dislike riding in the dark, I forget what damn gear I'm in. Its a relief to find a steep hill coz at least then I know in in gear combo 0
