Yeah, that makes sense. The Kreg jig moves up on thicker stock so that the screw will exit the stock in the center of the edge. That is why your screws are not centered in the piece. You essentially lowered the jig by raising the workpiece so it shifted the hole towards the edge.
BTW, you can get the screws in either head style in any length. Some stores just don't carry the complete collection. But like you said, one the glue sets, it does most of the holding anyway.
Here's a picture that I took which shows how the hole moves as I moved the board up and then drilled the hole to try to eliminate drilling through the top of the rail.
You can see how the holes moved nearer the edge of the board, which affected where the hole exited the edge of the board, as was posted above.
