On a related note; some of these language-twisters go it as far as inventing non-existing grammatical differences, only meant to deny everyone around them of ever being right. For example, over Lunch: "What? An Audi- you call that a car!? that's not a car, that's a VEHICLE! Now Porsche - THAT'S a car!"
Unfortunately, we are witnessing here a real-life management tactic: Always disagree with competitors when a senior manager is around. You can't directly fire competitors, but you can deny them of looking smart- like forever. Some low-level managers always deny their employees of the privilege of ever being right, sometimes hanging onto tiny grammatical matters or the usage of different wording to express the same idea.
In a related note- these people always agree with their managers, even if they say that night is day. Even if their manager says complete nonsense, they can still quote it word-for-word and sound like they deserve promotion.
