It's no secret anymore that Hollywood constructs movies in a modular way. They write and shoot a bunch of scenes and then they try to combine them in random ways and show the results to test audiences. The combinations which make the best score are pushed forward to later iterations of editing and, eventually, to a "final" cut for theatrical release.
The problem with this approach is that you get a disjointed set (not a sequence) of unrelated scenes rather than a wholesome story - in the best case scenario. Realistically, there will be cracks. For example, when a character references past events, it does not match what was actually shown (or, sometimes, what was later put into CGI - the actors don't know what they are talking about, those events never happened for them, they happened only inside GPUs of some server farm).
That's not how storytelling works!
