The effect is that, with the window open there's a gap at the hinge
side that's wide enough to get your arm through for cleaning the
outside of the window.

That's such a simple idea, and so easy to implement that I'm surprised
it's not more commonplace.

I expect another reason for doing them like that is so that they can
fold back against a wall even when the window is recessed into the
opening somewhat.
not in scotland you can't where the window is installed in the correct
position behind the dpc.....
