I have my own personal interpretation about this statement but just want to "throw" it out there to see what others think.
There has been a lot of talk about control in this thread - this is not a complicated topic - in all martial interactions, the goal is
to control in some fashion - after all, why would someone attack you without the intention of controlling you; or if attacked, why would you not want to control your attacker so they stop attacking you.
So logically the goal
is to control - and how you do that can vary from the purely overt physical overpowering to the covert and subtle taking of the other's center while you keep yours - bottom line is you are in control, and once you are in control, it is your choice as to throw, drop, or disengage.
All very simple really.
