Yes that a way to do it when you mill in X and Y and the tool axis is Z.
Because it’s a Weingärtner Rotomill MPMC (turn-milling machine) I can imagine quite well that the ellipse is milled on the jacket and that the milling axis lies on the Z axis. But it’s not clear in the question. We will need more information: a sketch, setup situation and more details about the tool.
