A wheel that turns in all conditions

I heard from you in a recorded lesson that Rabbi Shimon’s innovation that every event that occurs, if it occurs, will be canceled, etc., is built on the concept of logical causality as built on the timeline.
Based on this, I had a strange question: A person who sanctifies so that the Kiddushim will be performed, or a gift so that we can clearly know the validity of the Kiddushim, enters into ridicule again. Because causality in the timeline is: conditional validity> The validity of the kiddushin, but the postponement of the kiddushin depends on the validity of the condition and vice versa.
Thanks in advance.
