I’ve just noticed the photo is without the magnets… oops!
But yeah, I do it the same way - I attach them in front of the camera as far as possible so that the rope is stretched to a maximum (to avoid the camera bending backwards from the wind)
Edit: I forgot, that’s only the case for the two pictures I’ve posted above; but you can see the connection to the magnet in the front right part of the roof in the published Mapillary sequence I have linked above.
