The thing that confuses me is how they say setting a POSITIVE number for EV comp actually results in UNDER-exposure, and vice versa. But then I've heard people on this forum say that with certain lenses they always dial in +.3 or +.7 EV comp due to a tendency of the camera to underexpose. Aren't these two ideas in conflict with each other? Or does Pentax just not know how to explain it?

It’s the explanation. If you have correct exposure and dial in +1, the EV-meter will change and show that the scene now is underexposed. And thus you will have to change the shutter or aperture to get the correct (+1 exposure).
