Question for Transfers Across Teams

When I migrate from team A to team B, is it possible that the sub in team A and the sub in team B overlap?

For example, after the migration is completed, the sub of a user in team B is 820417.faa325acbc78e1be1668ba852d492d8a.0219. Will 820417.faa325acbc78e1be1668ba852d492d8a.0219 be the sub of another user in team A before the migration?
