Can't Union 2 Polygon

[gchling]

        Paths64 pathsTest = new Paths64 { subjs[0], clips[0] };
        Paths64 solutionTest = Clipper.Union(pathsTest, FillRule.NonZero);

The result solutionTest is not a polygon. What's wrong?
The Points of subjs[0] and clips[0]:

Your code got the right result. What is wrong with my code?
Path64 polygon1 = new Path64
{
new Point64(190000, 60000),
new Point64(160000, 40000),
new Point64(40000, 40000),
new Point64(40000, 160000),
new Point64(160000, 160000),
new Point64(190000, 140000),
new Point64(190000, 110000),
new Point64(150000, 110000),
new Point64(150000, 150000),
new Point64(50000, 150000),
new Point64(50000, 50000),
new Point64(150000, 50000),
new Point64(150000, 90000),
new Point64(190000, 90000)
};

        Path64 polygon2 = new Path64
    {
        new Point64(50539, 169430),
        new Point64(18939, 171185),
        new Point64(17830, 151216),
        new Point64(49430, 149461)
    };

        Paths64 polygons = new Paths64 { polygon1, polygon2 };
        Paths64 resultOther = Clipper.Union(polygons, FillRule.NonZero);

What is wrong with my code?

The orientation of your paths are currently opposing.
