If the two foci of the ellipse are coincident then the result is a circle. Ellipses with foci that are fairly close look very circle-like. It might be an ellipse but it would have been nice to have an explicit demo.

not all ellipses are circles. Circles, however, are a special case of ellipse in which the both foci coincide, which means some ellipses are in fact circles.

Technically all points on a circle are equally far from the center of the circle. Which means an ellipse is not a circle.
