As far as I can tell and I have NO inside knowledge of this but…

If you already subscribe to updates via your iphone Omnifocus Reminders calendar then just checking the box to Publish Due reminders as a calendar forces OF to write changes to that same calendar.

At least that how it works here.

If this is the case then the Subscribe in iCal button actually does nothing as it's already set up.

Sorry if this doesn't help you.

Good luck.
