Immediate Mode displays one torus, not two

I didn't find a more explicit title, but let me explain. 
I have the following code attached to a GameObject:

[ExecuteAlways]
public class CommandWidget : ImmediateModeShapeDrawer
{
    [Range(0, 360)]
    public float yaw = 0;

    public override void DrawShapes(Camera cam)
    {
        using (Draw.Command(cam))
        {
            Draw.Matrix = transform.localToWorldMatrix;

            Draw.TorusRadiusSpace = ThicknessSpace.Pixels;
            Draw.TorusThicknessSpace = ThicknessSpace.Pixels;

            Draw.Torus(Vector3.zero, Vector3.up, 100, 2, Color.cyan);
            Draw.Torus(Vector3.zero,
                Quaternion.AngleAxis(90+yaw, Vector3.up), 
                100, 
                2,
                Color.green);
        }
    }
}

This doesn't draw anything. But if I comment one of the Draw.Torus calls, the other is executed properly. 

I feel like this is a bug, but maybe I did something wrong :)
