It is a verified fact that 2 + 3 = 5 according to the semantics
of arithmetic. Anyone having an opinion that contradicts this is WRONG.
Sure, but that was not the first thing mentioned in the initial message.

Verified fact: the emulation is incorrect

Because P never calls H1(P,P) and P does call H(P,P)
the call from P to H(P,P) returns in the first case
and cannot possibly return in the second case.
