"This is referring to actual subs (bottoms) manipulating or steering play toward their preferred outcomes and overriding the Dom (top). Its not a battle of wills and the bottom wants to be the bottom they are just trying to engage the play they prefer."
pretty much sums up what i think "topping from the bottom"
Is it really not a battle of wills?
If it where not a battle of wills, the bottom would indicate her preferences and allow the top to decide whose preferences are going to take precedence hers (the bottom's) or his (the top's). When topping from the bottom, you get a sub using her female powers to manipulatively and in an evil fashion get her way.
