I could imagine someone inexperienced or whatever actually turning the camera to portrait orientation but in the opposite direction than what we consider "standard", so that the flash is coming from camera right -- after all, your right hand can still hold the grip and the finger can stay on the shutter and you can still look through the viewfinder, it's not like turning the camera upside down, and I can imagine plenty of people don't know the "proper way" to hold the camera
It isn't necessarily "wrong" to hold it that way with flash. I almost always shoot the conventional (shutter button high) way in portrait mode, but on a few occasions when I am shooting with a speedlight on camera, I may go the other way in order to position the flash at a more suitable angle. Depending on the angle to your subject, the flash can light them quite differently from being offset to your right instead of the left, particularly if you want to bounce it off the wall on that side.
Although I do avoid direct flash as a primary light source whenever possible, I do find it useful outside as a fill light and choose my "side" according to how I need to fill shadows or otherwise light the subject.
I agree, generally, with what you say but it sometimes pays to take the position of the flash into consideration. Oh, and my mates missus DOES use her camera upside down (admittedly it is only a compact not an SLR) because she is left handed and trying to use it normally finds she cannot squeeze the shutter button smoothly and tends to jerk the camera, so she uses it upside down and presses the release with her left thumb. Apparently it is what works best for her, but it does look damn peculiar.
