The intent is that if the application or upper-layer specifies a source address that is clearlyy illegal, then the network layer reports an error instead of sending a packet with an illegal source address. Here are a couple examples: a) The application specifies a source address of ff02::1. b) The application is sending to fe80::1%2, and specifies a source address of fe80::5. But fe80::5 is not assigned to an interface on link 2.
