Travel mode vs Recently deleted items

I've only one explanation to this - these are not deleted items per se, but the moved items. I.e. those I moved from my main (safe) vault to other vaults when I was setting up the feature (I'd been using a single-vault setup for many years). But the result is nonetheless the same. 

If this is true, then it's still a potential flaw because each time you move items between vaults within 30 days from your travel you risk having these items exposed in the recently deleted items list.
