Yes, they did. But it is not clear what that means - symmetrical along the length/narrowest part of the board or symmetrical around the reference stand? And if they meant the former, then that statement clashes with their official sales materials which state that the sidecut is set back.
Which one do you believe (assuming there really is a conflict)? I will go with the official materials - especially after the customer service guys recommended the 'between chin and nose' method for determining the correct board size...
Their website states setback, but doesn't go into detail on what is setback. When I had mine, the sidecuts were symmetrical, just the mounting points were setback.
