It is always correct for any simulating termination analyzer to

its own termination.

If HHH would correctly simulate DD (and the functions called by DD)
then the simulated HHH would return to DD and DD would halt.
But HHH failed to complete the simulation of the halting program,

 
HHH is only required to report on the behavior of its own correct
simulation (meaning the according to the semantics of the C programming
language) and would be incorrect to report on any other behavior.
