What is the ruling if a husband makes an unconditional divorce statement and then attaches divorce to a condition?

Primary text

If a husband states, "If I divorce you, you are divorced," and then attaches divorce to a condition, such as, "If you go out, you are divorced," and she goes out, then she is divorced by her going out, and then she is divorced again by the other conditional statement because he divorced her after the completion of the first condition (the going out).
