That maps the single point r = 0.1000... = 0.0999...
to both the point x = 0.1000..., y = 0.000...
and to the point x = 0.0999... = 0.01 , y = 0.999... = 1, and maps those
two complex points back to a single real point.

And similarly for all the infinitely many reals in [0,1] having dual
representation.
