The example actually says "This is a hotizontal text layout"
Also, I think you will find that Apple's OS X text input allows Japanese SOD.
English and European language speakers don't appreciate this, but one factor in Apple's success in selling computers and phones in Asia is that OS X does two-byte languages. Linux and Android does not.
By that I mean, sure, you can get Mac, Windows and Linux PC's to work in, say, Chinese, or accept input in Chinese, you can get a phone...
