And, if I understand correctly, this subroutine exists (and is felt / has effect on its host program) whether or not it “exists as qualia” in the particular sense that some clever arguer wants to define qualia as anything other than that subroutine. The fact that there is an effect of the subroutine is all that is required for the subroutine to exist in the first sense, while whether it is “the subroutine” or only a mimicking effect is only relevant for the second sense of “exist”, which is irrelevant to you.

Is this an accurate description?
Pretty much, as I don’t consider this “second sense” to be well defined.
