If you look at it like a dot on the bottom and a dot on the top of a middle-mouse trackball then what you said would make sense. Then if you chose to have the system register the bottom dot, moving the ball up would move the dot down. If you chose to have the system register the top dot, then moving the ball up would move the dot up. Then, as you said, if you chose to have the system register the bottom dot, moving right would move the dot left.
However from another standpoint - you are still directing your middle finger left for looking left and right for looking right even when looking at it as if it were a hand on a head.
It is also more like a flight stick and games like descent were around and popular back then. I used inverted Y-axis on that with mouse before I got a serial port flight stick and then used inverted on that too obviously.
Also, some games actually have flying (or controlling a turret, drone, etc) portions within the game where the game swaps to flight stick inverted Y axis mode automatically so it could be easier to just keep it that way globally on those. It would feel odd to fly, operate drones, turrets etc in games without inverted to me even if it were an option.
Incidentally, I used to play with an old school microsoft (and later logitech) thumb-ball mouse at one point - and with great accuracy once configured properly. I always inverted in game on those as well but I never swapped the X. However I bet I could get used to swapping the X-axiswith enough practice if I really wanted to.
This is what it looks like explaining the "logic" behind using inverted free look in an FPS.
Left/Right on the joystick in an airplane controls the roll, not moving left/right. It's a completely different system and makes sense and feels natural in it's own way. Normal flight games don't do full free look with a joystick and simply invert the pitch,
There is no logical reasoning to using inverted free look in an FPS. If you used inverted it's because you got used to using a janky, unnatural system and don't want to change. That's fine, it doesn't actually have any disadvantages over normal controls once you're used to it. You're just going to have a tough time when you try to play a game that doesn't support it.
