I am not sure what your question is, but the issue is about performing
compilation semantics in interpret state. An implementation of IF
containing ?COMP (or equivalent, like Albert's preamble) will fail
then, while it will likely work if the ?COMP is removed.
That's the general problem with STATE-smart words: they check STATE at
run-time instead of at parse time. It works when the word is
text-interpreted directly (because then the run-time is performed
right after parsing), but it can fail if the run-time is delayed by
ticking or POSTPONEing (or [COMPILE]ing).
