I'm sorry, I don't know and I can't completely explain what you've observed.

No need to recall anything since it's documented in https://trac.macports.org/wiki/Migration. That document is geared toward migrating from one OS version or architecture to another, but it could be enhanced to address the case of migrating from one machine to another while keeping the same OS version and architecture. If you'd like to make those enhancements feel free; anyone can edit the wiki.
