Given that, I would say that no, snoozing an email and archiving it are different things, regardless of the snooze duration. With my workflow, I archive any email that no longer requires my feedback, so anything that is still in my inbox would probably be the same as one that has been snoozed anyways.
If you're snoozing messages forever, you may want to reconsider your approach to managing your inbox. Snoozing a message over and over seems like a lot of wasted action. Why not just leave it in the inbox if it's short-term or set up a calendar reminder if it's long-term instead?
