It seems to me that right() always turns the turtle clockwise, both with the "standard" and the "logo" mode.
I agree that changing left->right and leave clockwise is better than changing clockwise->counterclockwise.
I don't think it's worth mentioning the mode here.
(On a side note: I was expecting the 'turtle' to be an instance of some Turtle class defined in the turtle module, or perhaps a singleton, but it turned out that in 'turtle.right()' turtle is the module itself.  It might be better to say something like "After importing the :mod:`turtle` module, ...".)
