Operations in an alleged original program that don't affect I/O in any possible case are just junk, functionally equivalent to null operations. They don't play a role the isomorphism. Compiler writers will tell you that computations that have no effect at all on I/O behaviour can be optimized out. Evolution would be similarly ruthless in deleting structures that have no effect on behavior, except to uselessly consume metabolic resources. A bad programmer might have included nonsense loops in the original program that did nothing but bloat its size and waste execution time. A good programmer or compiler whould clean up such code, leaving only the essentials to produce the proper I/O. A program reverse-engineered from a HLT might resemble a program written by a good programmer. But, with or without junk code, all encodings of the same I/O behavior are isomorphic.
