What reasons could there be for the {pi} binding to not catch a few of my multi-part movies
There are countless possible reasons. If you provide
file paths as text so I can run a few tests and see what the cause might be in your particular case.

As it turns out of the 6 movies in question 3 were legit duplicates and not parts of a multi part, so props on you software recognition for being smarter than me lol.
When I debug these things, I sometimes come to the same conclusion.

Gone with the wind and godfather have the two parts at exactly the same filesize, might be the issue? Different lengths though. But La sociologie est un sport de combat as neither the same length nor the same filesize so i'm lost.
The media characteristics can make a difference. The file size doesn't matter, but multi-part movie files ideally all have the same video codec, audio codec, same resolution, comparable duration, etc.
If it's indeed related to media characteristics, then the
MediaInfo Inspector might be able to shed light on this phenomenon:
