I think that was also my understanding and took the risk of not
answering the right question. I just didn't think it is common to store
copies of sent mails in different places, but why not?

The tagging feature here is news for me, I have that done by running a
postsynchook script from offlineimap, (adding a sent tag I mean). So it
means I could have "kth/Sent +sent -inbox" as string for example?
