That's what we've got now and what would be expected, however...

The command is 'FREEZE', which sounded to me like the transaction ID
would be set to FrozenXID, meaning that we wouldn't be able to tell if
the inserting transaction was before or after ours...
Your analysis of the hint bits themselves sounds reasonable but it seems
independent of the issue regarding setting the actual transaction ID.
