To add to that, my theory is that our subconscious can process the probability that someone will appear in front of us and send that probability to our conscious mind. For example:
Maybe from a few weeks ago, your subconscious started picking up on cues, either from him or the world in general, that may lead to said person waking up late/having a digestion problem/any chain of events that increase the probability of him being late for that interview & shows up the moment you thought about him.
The anti-recon scripting, alongside other scriptings, might help clear up the blockages that end up making you have a better connection with your subconscious, leading to it giving you “pings” about the higher possibilities that something will happen at a certain time.
In this case, although it doesn’t tell you explicitly when or why, it was able to convey the idea about the french guy in general to your conscious mind.
This scenario is well within the realm of possibility, as the subconscious is not well understood and is stronger than we think.
