What lens are you using? What focal length are you using when this happens? Does it matter? Need some more info about your shooting and lighting conditions, camera settings, etc.
I have never used that particular lens. I do use the 600EX II-RT. It is able to adjust the dispersion pattern of the light depending upon the focal length of your lens. When I use a wide angle lens, then the dispersion.
As far as which direction it points when when you double click, I assume that behavior is part of setup and configuration. Do you have to change it to a different mode where it bounces lithotripsy off the surroundings.
The initial direction could also be your caused by your ambient lighting, or some other incidental factor. It could be taking infra-red light measurements for all i know. Maybe walls and ceilings are too far away for it to sufficiently light the subject by bouncing the light off the walls or ceiling.
The Speedlite 470EX seems to no longer be listed at the Canon USA Online Store and a couple of other places. I think your issue could involve a memory preset. Check out how Rudy Winston describes the functionality of the preset feature in this video.
