@OmarShehata they don’t have to create 2 lines, but they have to define more positions in the polyline.

Like this:

viewer.entities.add({
    polyline : {
        positions : Cesium.Cartesian3.fromDegreesArrayHeights([0, 0, 0,
                                                               170, 0, 0,
                                                               -100, 0, 0]),
        width : 10,
        followSurface : true
    }
});
