Is the phrase "He travels, marries immediately, and divorces the old one" considered a conditional divorce, and is the occurrence of a conditional divorce limited to specific wordings?

If a man says to his wife: "If such-and-such happens, then my wife is divorced" or "If you do such-and-such, then you are divorced," this is a conditional divorce, and it takes effect upon the fulfillment of the condition. As for the wording mentioned in the question: "What could happen if the aforementioned matter comes true," no divorce results from it, because it is neither an immediate declaration of divorce nor a conditional one.
