The problem might be clearer by asking what the subject and object of bf:hasHoldingOrganization statement are in this example.
The subject is apparently a blank node bf:Organization and the object is something with "organizations/dlc" as an identifier. That's odd. Presumably the item (which IS identified) should be the subject instead of the blank node.
I agree that the concept of "Authority" shouldn't be dragged into this particular example. Statements involving the bf:hasHoldingOrganization property should be understandable without it.
