Earlier in the same section, the text says:

        “Since the clone uses the same local description as its
        parent, creating a clone will fail if it is not possible to reserve
        the same resources for the clone as have already been reserved by the
        parent.”

> If the non-local (reflexive?) candidates are allocated using STUN on a per-port basis, addresses could be different too.

My assumption, and understanding of the text, is that a clone is a… eeeeh… clone - meaning that the local address is the same :)
