understanding the diode demodulator circuit?

When the diode is reverse biased, it carries no current, so the headphone carries it all. When it is forward biased, it takes the current the current and the headphone carries none.

I have always wondered why some folks put the diode across the headphone instead of in series with it. Most of the crystal radio circuits I have seen put the diode in series with the headphone.
