Professional JavaScript for WEB developers P226

As I understand it, (Object.getname = object.getname), this statement returns the right operand at the end of execution object.getname, but the key is where does the right-hand operand now be? I guess because this statement is executed in the global, there will be a temporary variable in the global, it may be named temp, and temp = object.getname; In fact, both temp and object.getname point to the same function, the logic of which is function () {return this.name};

If temp is anchored to the globle, the execute this is to point to the window, if it is anchored to the object, the execution of this is pointing to object, I do not know this understanding right?
