Oh, so one can sit at home enjoying a drink while one's reflection runs around trying not to get killed.
I have two explanations myself:
#1: The picture is made first but, before the trailer was made someone changed how Samurai looks because that someone found that looked better for some reason.
#2: They are identical twins who like to be chromed the same way. In the long run that gave them too many problems when people got them confused. When one of the identical twins got a cut in the eye brow over one eye, the other got one made too but over the other eye so people got a chance not mixing them up. Now people are killing each other over which twin has a cut over this or that eye.
Btw, the color on the inside of the jacket collar looks like some kind of light so it could easily be some RGB LED lights, after all it's in year 2077.
