Yes, sorry, I was somewhat deliberately vague here because it's not as
simple as the ordering in the seed file. (I had previously believed this to
be the case, but Colin set me straight recently.) What's really required is
to make sure the package you need is *topologically* before the package that
carries the ORed dependency. I don't know a good way to determine this
without introspection of the apt commands being run as part of the live
build.
