This consideration is kind of outdated since I wrote this before the electronic distribution of BIs by LEGO themselves. This is primarily why I'm considering dropping the practice of adding BI steps to my OMR models and switching to something more sensible for model organization.
For a more direct answer to your question than what I gave below…yes, my submodels are based on actual building steps, but not named for them. Instead, all the steps in my model are based on the official instructions. If a sub-build appears at a step in the instructions, then I'll include it at the same step in my model. And if the sub-build has its own steps in the instructions, I'll have the same steps in my model (so sometimes there's a blank step, if the instruction doesn't add any parts but only rotates the view, e.g.).
