The addition of support for left and right arrow keys in radio groups was 
intended to match the current behavior of radio buttons in the browser. 
Currently up and left arrows move to the previous radio in the group and 
right and down arrow keys will move to the next radio in the group. Note 
that the wiki has up/left moving forward and right/down moving backwards 
which I believe is opposite of the current behavior and hopefully just a 
typo. 

I think you are suggesting that only one set of arrows be implemented - 
either up/down and left/right.   My feeling that supporting both was 
accommodating to all users.  I believe that a visual l person encountering 
a horizontal grouping would assume left and right key navigation and up 
and down key navigation for a vertical orientation.  By supporting both 
sets the person who can not perceive the orientation can use either set of 
keys.
