How to move CircleGeometry in 2D scene and 2.5D columbus mode?

Hello, I want move CircleGeometry in 3D, 2D and 2.5D. This code from https://groups.google.com/forum/embed/?place=forum/cesium-dev&showsearch=true&showpopout=true&hideforumtitle=true&parenturl=http%3A%2F%2Fcesiumjs.org%2Fforum.html#!searchin/cesium-dev/translate/cesium-dev/dSydY8q6CLo/BNwMrziywS4J work in 3D:

var viewer = new Cesium.Viewer('cesiumContainer');
var scene = viewer.scene;
var primitives = scene.primitives;
var ellipsoid = scene.globe.ellipsoid;

var positionOnEllipsoid = ellipsoid.cartographicToCartesian(Cesium.Cartographic.fromDegrees(-100.0, 40.0, 0.0));
var circleGeometry = new Cesium.CircleGeometry({
    center : positionOnEllipsoid,
    radius : 90000.0
});

var circleInstance = new Cesium.GeometryInstance({
    geometry : circleGeometry,
    id : 'circle',
    attributes : {
        color : Cesium.ColorGeometryInstanceAttribute.fromColor(new Cesium.Color(1.0, 0.0, 0.0, 0.4))
    }
});

// Add sphere instance to primitives
var circlePrimitive = new Cesium.Primitive({
    geometryInstances : circleInstance,
    appearance : new Cesium.PerInstanceColorAppearance({
        translucent : true
    })
});

primitives.add(circlePrimitive);

function moveDome(circlePrimitive){
var inverseModelMatrix = new Cesium.Matrix4();
Cesium.Matrix4.inverseTransformation(Cesium.Transforms.eastNorthUpToFixedFrame(positionOnEllipsoid), inverseModelMatrix);
    var cartesianPosition = ellipsoid.cartographicToCartesian(Cesium.Cartographic.fromDegrees(-102.0, 50.0, 0.0));
    
    var modelMatrix = Cesium.Transforms.eastNorthUpToFixedFrame(cartesianPosition);
    Cesium.Matrix4.multiply(modelMatrix, inverseModelMatrix,circlePrimitive.modelMatrix);
}

Sandcastle.addToolbarButton('moveCircle', function() {
    moveDome(circlePrimitive);
});

But when I morph scene to 2D or 2.5D, CircleGeometry come back to former place. In 2D and 2.5D moveDome() visually no effect, but when I morph scene to 3D the circle go to right place.
