Yes, that's correct. It was easier to implement it that way

I'm a bit confused about what am does when you pass extra options to
--continue. It looks like they do not persist if there's another
conflict and may only apply to the first patch that is applied when
resuming - I'd need to spend more time looking at the code or run a test
to be sure.
