Its the whole point in using Kamisoris the traditional way!! The angle!
Taken from the previous page:
"Kamisori are used with one specific side against the face at all times. That side is the unstamped "Omote." The stamped side, which has a much more pronounced concave, is the "ura" and it is to be used away from the face.The use of Kamisori is a tradition. It is the way it is. [...] If the use was, as you would like, symmetrical, then the blade would be symmetrical.
Adding to the fact of what I pasted even Iwasaki says
The bolded part is angle to the face, it and the Japanese original text are not discussing sides. A low angle can be achieved with either side."If you try using a razor at a standing angle, the edge will very quickly start to show signs of
damage, and an edge that should shave 200 faces or more will only shave around ten. So if you
think you'd like to preserve your edges as long as possible, keep the blade as flat as you can when
you shave."
Hence not using the other side just sticking to one side will make the edge last longer. So shaving the traditional way with a Kamisori is meant to make a Kamisori edge last longer.
One youTube vid is titled "130 years in Business: Japanese razor shaving from Barber Yanagi" Then the guy shaves the client with both sides.
