Its Anode and Cathode.. The resistor should be on the Anode.. But, the other thing is a Diode, a one way gate... so what they've done here is made it so you can't hurt it if you connect it backwards. The diode acts as a one way gate, so if you hook the led up backwards, the current won't flow and you won't fry the led.
