It's important to remember that DAD is link local. It is only checking whether the same address occurs on the local link. Duplicate MAC addresses are not actually a problem as long as the duplicates are not on the same link. If the duplicates ARE on the same link, then you have a real problem at layer 2 anyway. The same link local address, based on a MAC, is also a real problem if it's duplicated, for much the same reason.
