Unique is unique. There is no other record that could possibly be identified by the same unique identifier. It doesn't matter if you can identify the same record using other identifiers that are also unique, it's still a unique identifier. So if you have a unique identifier for your table you can use on the OLD row in the WHERE clause.

For example, if you have a primary key on that table you can use it to identify the records for the update. Whether that PK uses a simple unique index or a composite unique index doesn't matter at all either.
