Trust the datasheet. And you can crosscheck with the schematic of your particular Arduino.
D0 is PD0 which is pin 2 of the 328. D1 is PD1 which is pin 3, etc. up to D7 is PD7. As you can see, the pins on the IC itself jump around. Then D8 is PB0, etc.
So the answer is yes and no. You will have to determine by looking at the schematic of the Arduino you are using which pin on the IC you need to connect things to.
