I'm not totally clear about this, but I think that Stata expects a loaded program to have no commented-out text. That is, any commented-out text it finds at load time is stripped out; once loaded, a program has no comments. (Do -program list-; you will see: no more comments.) But now you are introducing a new twist: parts of the program become commented-out at run time. Perhaps the comment-skipping feature does not operate (at least, not completely) while running a program, as it is presumed to have already gone through that step at load time.
