Yes that is about it. The closed gun waiting for birds with the muzzels pointing up is very common now. It seems to be more so as the O/U has become the gun of choice on all but the very best shoots. This is I think because the gape makes them slower to close and also that people are becoming more anxious to shoot their "share" of the bag as shooting becomes more expensive and people take less days each year. And also people use their guns less and are less familier with their handeling, it is concious thought and not second nature.
However unless rough shooting alone it would be very much frowned on to move through woods or cover with a closed gun.

Yes indeed, I was discussing it in the shotgun context rather than the DR. The point about re-engaging the safety is well made, that is why I like non auto safeties as you never assume it is on unless you did so yourself.
