You're still not getting the question.
And besides, incident metering works the same, whether the light source is millions of miles away, or two feet from your subject.
The question is why, if you measure at your subject (which you certainly should with a light two feet away from the subject), will the reading stil be correct if you set the cmaera up two miles from your subject.
The light seen by the camera has to travel those two miles after being reflected off the subject.

So before anyone else gives the same non-answer you gave, tell us why you can use the same setting you should use with the camera not two miles, but six feet from your subject.

It's easy enough to do that, since the answer has been given a couple of times now.
And it's definitely not "the light source the Sun is a fixed distance away, and since you are measuring the light falling on the subject not reflected of the inverse square law is irrelevant".
