Why do we use ^ operator when overriding GetHashCode method?

I was watching a video where we override GetHashCode method like this:

public override GetHashCode()
{
    return this.Name.GetHashCode() ^ this.Id.GetHashCode();
}

Why did we do that here to get the new HashCode? so why XOR operator between those two variables?

Here is the video:

@Abion47 Except it introduces an undue risk for potential collisions in many contexts, it's just easier to type that methods that actually do it more effectively. – Servy May 17 '17 at 20:36
