Transient Storage in DB

With the Object Cache settings, I want to clarify this checkbox:

———–
[]Store transients in database
Use that to store transients in database even when external cache is used. That allows transient values to survive object cache cleaning / expiration
————

This setting stores a copy of the transient in the database AS WELL AS in the object cache, right? It doesn’t prevent the transients from being in the object cache… it just stores them in both places, right?
