If adjusted properly how do the towed vehicles brakes overheat unless the coaches brakes also overheat? You have to be constantly decelerating for the surge brakes to be constantly applied.
What am I missing?

Going downhill the toad is getting a constant deceleration that is a fraction of gravity and thus the surge brakes are partially engaged.
As you mention, however, there is a feedback mechanism of sorts: The fractional g will cause the brakes to engage pulling the car back disengaging the surge brakes. At some point the system will find a steady state of partial brake application.
Gritz: We get no clunking at all with the surge brakes on our EZE Tow. It is a hydraulic proportional system and not an on/off thing. Thus there is very little movement in the tongue when the brakes engage or disengage (even slightly). I probably get more clunking/slack in the play of the receiver in the hitch than with the surge brakes.
