Perhaps this counts as optics, but I see it as a way of offering evidence to the outside world that the feeling is mutual. If you were satisfied with the job/conditions/policies, then you might choose to continue to try to stay employed there.

Of course, it's not strong evidence because nobody knows how much choice you had in the matter. If you quit when you have a 75% chance of being fired, that means something different than quitting when you have 100% chance of being fired in the next 30 seconds, and the outside world doesn't know which is the case.
