Moving the cursor to top left corner of the screen in C# Winforms App

Question

I have a MainForm which opens a modal dialog using ShowDialog() method.

In that modal dialog class Form_Load method I have:

    private void Form_Load(object sender, EventArgs e)
    {
        this.Cursor = new Cursor(Cursor.Current.Handle);
        Cursor.Position = new Point(0, 0);
    }

I found above code somewhere in internet searching for information about moving the cursor to 0, 0 position.

If I remove code this.Cursor = new Cursor(Cursor.Current.Handle);, it also works, moving the cursor to 0, 0 position.

What is that cursor creation used for? should a border condition exist somehow when the app will be used?

Thanks Jaime
