Hmmmm, NatalieD, you may be right but I have a problem that terms here seem to be flexible to the point of being meaningless. I agree that there has to be some wiggle room in terms that are used to describe different aspects of our life but they are usefull.
Tom is correct in his term with the case he stated but so would bottom be and neither would be exclusive to that person. topping from the bottom mearly means that the bottom is in control and for those that aren't into trusting enough to give up control but wish to experience some fantasy of being a submissive it is common practice.
To say that request or suggestions by a sub/slave is topping is absurd, that is different from do me my way. I have learned different techniques to please a lovely sub/slave and in doing what she needs I am still the one in control.
