What is in $du if you log it right after handle_ruri_alias()?
Maybe you overwrite it somewhere later?

If you print $du in the logs after calling handle_ruri_alias() you should see what you expect (if you previously called set_contact_alias)... Or you can call set_contact_alias on not call handle_ruri_alias. Two ways of doing the same.
