Yes. I've found that this approach is definitely flawed. It works
great for a single image build. Outside of that it acts funny, like
you mentioned and can return incorrect results. I'm planning on
revisting this soon.
I'm suspecting that your suggested approach is the way it'll have to
be. Looking at what is generated by various runs and I see issues.

Yes, agreed.
