That's dumb.

A second theory of mine is that, as you perform RC's throughout the day it forms a habit. With this habit also comes the "habit" of the RC's working since you are not dreaming. So I believe that if you RC just out of habit in a dream, odds are high that it will work, just as you would expect it to.
Like everyone else said, the idea is really just to stop and ask yourself if you are dreaming. The physical check is just to assure yourself that you are, in fact, dreaming.
