What is the legal effect of a husband saying to his wife, "If I divorce you, you are divorced," and then saying, "You are divorced"?

Primary text

If the wife has been consummated, two divorces take effect: one by the immediate utterance and the second by the conditional statement, as the first pronouncement fulfills the condition for the second. If the wife has not been consummated, she becomes finally separated by the first pronouncement, and the second one does not take effect because she is not in a waiting period and cannot be taken back, meaning any subsequent divorce must be irrevocable (Ba'in), and a divorce cannot be pronounced as irrevocable upon a never-consummated wife unless it is already an irrevocable separation.
