What I understood from the comment "the bad guy controls the technique used" was, that depending on which way the guy resists, or what he decides to do next is of no matter, as either "over" or "under" will work (dependent on the direction the "bad guy's" force takes).
Being generally smaller and lighter than most people I work out with, it makes more sense for me to use their force against them instead of using mine.
If I was bigger it would be of no concern, as I could impose my will whatever the situation. Unfortunately this is not so!
I do not perceive the concept as a "receiver" mentality because (in theory
) I already control the situation, I'm just not set on what "technique" to use.
