JR,
Because it is using the equation of a parabola y=a*x^2, not equation of a hyperbola
An ellipse has (x/a)^2 + (y/b)^2 = 1
A circle is a special case of ellipse with a = b = r (x^2 + y^2 = r^2)
A hyperbola has (x/a)^2 - (y/b)^2 = 1 (note the minus sign and is not the same as a parabola even if it sort of looks similar).
