[Med] As you can read for example in https://tools.ietf.org/html/rfc6052#section-4.2 or https://tools.ietf.org/html/rfc6724#section-3.2, these addresses are handled as IPv4 ones. This would allow to use DHCPv6 to communicate both IPv6 and IPv4 addresses to reach a dual-stack DOTS agent.

[Med] The intent of the sentence you quoted is to avoid such behaviors and allow to use such addresses as per the RFCs listed above.

[Med] Fixed. Thanks.
