Connecting the Hall Effect Sensor.

I've been having abit of a problem connecting the hall effect sensors with the 4 pins. i looked at the file on http://www.allegromicro.com/datafile/0660.pdf and it said that one pin is for +v one is for GND and one is the output signal and the one left is also for GND . it seems a bit weird to me. perhaps i'm not understanding it correctly. why would you need two pins for GND. do you really have to connect both the 3rd and the 4th pin to the GND?

please help me figure this out. what is the correct way to connect it?
