Yeah, if a janitor cleans up a bad tag, it will be deleted your end within a day or so, even if you were the original uploader. No worries, sending typical booru tags up to the PTR is a good and useful practice.
Siblings and parents work a bit different since a janitor needs to approve to add them in the first place. In that situation, where the sibling or parent was never approved to be added in the first place, your client keeps them. But if you add a sibling, and it is accepted (and hence sent to all users, including, redundantly, to you), and then it is later deleted or reassigned in some way, you will get the deletion update.
