Ugh.  Google seems to confirm your thought that Oracle expects

which is not the way we are doing it.  Not sure if it's worth trying to
fix this --- the conversion pain would be significant.  I agree we gotta
document it, however; will go do so.

Note that in the Oracle worldview it still wouldn't be sensible to use
a negative step.
