Do game journalist get Pulitzer Prizes? Has that ever happened? Who are you people and why are you in my room?
That was my first thought too. We're a loooooong way off the world taking game journalists remotely seriously enough for them to win Pulitzers.
This is where it turns out someone has and I'm just flaunting my ignorance

The problem is it's really pretentious and there's already a suitable English term for it (gameplay and story segregation, as noted above.) Authors making up pseudo-latin words for things instead of just using English is the thing I most hate about reading 18th and 19th century documents, and it's even more obnoxious now than it was then. I saw one particularly bad example a while back: "cathexis." It was used in some paper someone wrote on ancient Rome. When I went to look it up, first I found the meaning (it means "the process of investment of mental or emotional energy in a person, object, or idea"), but then I found where it came from. Turns out some d-bag translator made it up instead of just using the German word "besetzung" when he was trying to translate the works of Sigmund Freud and found out that word had no suitable English translation. He made up a word out of wholecloth instead of just using an existing one and inserting a footnote to explain it. Yeah.
The Ludonarrative bit I'll grant you is pointless (personally I quite like it, but I just like "ludic" in general, it's a tasty word). Call it gameplay-story, or gameplay-narrative it works jsut as well.
Segregation vs Dissonance though refer to subtly different things.
Segregation implies seperation, and refers to the game content. The vast majority of games have some element of segregation and it can be an entirely neutral or even a good thing. It just means there are elements involved in the gameplay that aren't involved in the story or vice-versa, can be as simple as "Being in a cutscene" or not tying yourself in knots trying to explain why fighting someone involves completing Match-3 puzzles

.
Dissonance on the other hand, implies something noticable, obvious and unpleasant, and refers to the player's experience. It's when something in the story and gameplay is actively contradictory to the point that you notice it and it distracts you or pulls you out of the experience.
