Perhaps, but when a big part of the meme is to literally buy two tickets and watch both films that just seems way too consumerist to come around naturally. Like wow, the main theme of it just so happens to be getting you to act just how the studio executives would want you to, go figure. Maybe I’m reading too much into it, but box office ticket sales since the pandemic are still recovering, so I would not at all be surprised if these sort of tactics were being used to drive sales. And its not entirely free advertising for Nolan’s film, since the whole point of the “Joke” is the absurdity of watching both films despite their vastly different subject matter. It just seems to me like the prefect opportunity to piggyback off each other’s popularity.
