That the first plots the asymptote is an illusion caused by the plotting
routine generating a single Matrix of points representing a continuous
plot, when, in fact, the curve is not continuous.  Because the second
curve is even around 1, connecting the points adjacent to the
singularity does not form a "pseudo-asymptote".
