H can abort its simulation of D and correctly report that D

DDD is correctly emulated by HHH until HHH sees the same
never ending pattern that anyone else can see.
Maybe HHH really sees a never ending pattern but that pattern is not
contained in the behaviour specified by DDD and therefore not relevant.
When DDD correctly emulated by HHH keep repeating
its first four instructions because it calls HHH(DDD)
this does prove that DDD cannot possibly reach its
own "ret" instruction and halt, thus DDD correctly
emulated by HHH <is> non-halting even when it stops
running.
