No, it is correct to report that HHH is unable to correctly simulate this halting program up to its end.

 In other words you are totally clueless that infinite
recursion HAS NO END.

 Do you mean that having no end enables the simulation to the end?

 see my new post
DD emulated by HHH cannot possibly terminate normally --- x86 code

 In that post:
 

DD()
[00002133] 55         push ebp      ; housekeeping
[00002134] 8bec       mov ebp,esp   ; housekeeping
[00002136] 51         push ecx      ; make space for local
[00002137] 6833210000 push 00002133 ; push DD
[0000213c] e882f4ffff call 000015c3 ; call HHH(DD)
[00002141] 83c404     add esp,+04
[00002144] 8945fc     mov [ebp-04],eax
[00002147] 837dfc00   cmp dword [ebp-04],+00
[0000214b] 7402       jz 0000214f
[0000214d] ebfe       jmp 0000214d
[0000214f] 8b45fc     mov eax,[ebp-04]
[00002152] 8be5       mov esp,ebp
[00002154] 5d         pop ebp
[00002155] c3         ret
Size in bytes:(0035) [00002155]
 When we hypothesize that the code at machine address
0000213c is an x86 emulator then we know that DD
remains stuck in recursive emulation and cannot possibly
reach its own "ret" instruction and terminate normally.
 When we add the additional complexity that HHH also
aborts this sequence at some point then every level
of recursive emulation immediately stops. This does
not enable any DD to ever reach its "ret" instruction.

 The question remains unanswered. If the author cannot tell what he
means we may assume that he didn't mean anything.
 

 Your question applied to my ambiguous verbiage.
I cancel that ambiguous verbiage and say that
DD emulated by HHH cannot possibly reach its
own "ret" instruction.

You should also say that the words you intend to retract are "In other
words you are totally clueless that infinite recursion HAS NO END".
Until you do so my question is valid.
