When verifying a snapshot, what does "--sources" do?

As the title says, what does “–sources” option do? It says “Verify the provided sources”. What does that mean?

Okay, I may have figured out what --sources does, but someone will need to confirm for me. By default, Kopia checks all sources when using the snapshot verify command. --sources allows the user to force Kopia to only verify certain sources. Correct?

Yeah, I think that you can provide multiple sources to snapshot create and haven them verified distinctively. However, since all of my snaps are single source, I couldn’t verify that.
