fly out supersedes declared out ?

[UmpTTS43]

My mechanic on this would be to point at the BR and say "that's passing." After the outfielder has complted his play, catch or no-catch, I would make the appropriate call. On a catch, I would vebalize "that's a catch." On a drop, "no catch. you, pointing to BR, are out for passing." If a coach decides to come out in either situation, I would stop him and confer with my partner just to make sure we were on the same page.
