*THIS SEEMS WAY WAY OVER YOUR HEAD*
It is contingent upon you to show the exact steps of how H computes
the mapping from the x86 machine language finite string input to
H(D,D) using the finite string transformation rules specified by
the semantics of the x86 programming language that reaches the
behavior of the directly executed D(D)

The first six steps of this mapping are when instructions
at the machine address range of [00000cfc] to [00000d06]
are simulated/executed.

After that the behavior of D correctly simulated by H diverges
from the behavior of D(D) because the call to H(D,D) by D
correctly simulated by H cannot possibly return to D.
