Like all racers I also ski in very narrow boots, so maybe this skews my reality. I rarely, if ever, boot out, and I like to think I ski with above average edge angles.
I tend to notice that skiers who are constantly complaining about booting out are skiers who are either exagerrating their angles, A-framing, grinding on the outside ski to get it to carve the turn, or just generally out of balance with the outside ski. I also try not to confuse booting out with the snow surface giving away under the load from the ski. Soft snow and skinny skis can create the feeling of booting out, but it is not booting out because all the lift in the world won't save you if the snow you are skiing on crumbles under the load you are putting on it. Wider skis help in this instance because they spread the load out over more surface area.
This has pretty much been my experience as well; having once thought I would boot out. It turned out I was just too far inside, my balance not being directed to the ski/board, really.
I guess I think of true BO as being balanced over the outside ski/turning edge well, and
having boot/snow contact disturb things to a disruptive degree, whereas leaning/moving in so far that weight is transferred to the snow through the boot instead of the ski/board is just being out of balance.
It used to happen to me on a snowboard pretty badly until I learned to really direct balance to the edge, then when my boot toes dragged a bit it wasn't disruptive anymore. I think it is much the same with ski boots, if the snow crumbles or what have you, if I am balanced over my edge(s), a little boot contact is not an issue.
The one situation where the above does not apply is badly mismatched/stanced snowboard gear, which I see a lot of lower level/new riders out on, so I guess to be specific I should qualify that I would still experience the feeling of boot out with properly set-up gear due to balance issues.
Your first photo is a pretty good example of "alleged boot out," the actual culprit being balance directed to the snow somewhere between your outside foot & body instead of balance being directed to your ski's edge.
The 2nd pic is a great example of what can lead to alleged boot out, the hips being back so the skis don't hook up, or stay hooked up so the skiers thinks they need to move inside to hook up the edges better which ends up =ing pic #1... IMHO
