THE ONLY FREAKING THING THAT NEED BE KNOWN
ABOUT THE CODE AT THAT ADDRESS
(TO DETERMINE THE SEQUENCE OF MACHINE INSTRUCTIONS OF DD)
IS THAT IT EMULATES THE MACHINE INSTRUCTIONS OF DD.

Not necessarily. A good decider would prevent infinite recursion and base its decision on other facts and then return.
