Logic has nothing to do with this scenario, Mike. The jack was intended for use as a mic input, with the added feature of a "line" switch so you could play other signals through it. Producing a stereo signal wasn't on the draawing board.
This is getting soooooooo tiring.
Believe what you want, but if you plug anything into a psr2000 mic input - you will enjoy lovely, Phil Spechter-like, MONO sound.......processed through a decent STEREO effects unit.
Forget about logic.
Forget computer line ins..
Forget about getting stereo from a mono device.
It just ain't gonna happen, my friend.

I'll respectfully drop this now. I'm sure it's wasting good bandwith, and I can't explain it any simpler. It's good to question things, but there are times when you run straight into the answer, and you need to recognize that it may not be the answer you want. This may be one of those times. The answer is:
M
O
N
O
