Usually all control surfaces operated by mechanical means (cables push rods etc) such as is found in most aircraft other than large power assisted airframes are based on what is called a closed loop system. Basically that means the control surface can be operated from either end of that closed loop, IE the control column or the control surface itself.
'No Push' means just that, doesn't apply to a control surface as you could actually 'pull' a control surface to one side so 'no push' is irrelevant here:-)
