Ancora su ritorno di un reference

Ho questa funzione di overload di operatore:

const int &Array::operator[] ( int subscript ) const
{
return ptr[ subscript ];
}
Array è una classe per creare, gestire vettori:

class Array {

//...

private:
int *ptr; // points to the first element of array
};


Non arrivo a capire una cosa.

Per me ptr[subscript] dovrebbe essere un intero, perché allora la
funzione non è:

const int Array::operator[] ( int subscript ) const
???

Grazie
