You're right, I didn't look it up. I was remembering high school geometry.
From wikipedia:
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. It generalizes a circle, which is the special type of ellipse in which the two focal points are the same.
Not being a mathematician myself, I will die on the hill that says if two points are the same, they are one point.
