Each DS18B20 has a serial number, so the temperatures from each are reported separately.

1-wire is also called Microlan by the manufacturer... the idea being that each device uses a unique serial number and behaves like a slave "HOST" on the 1-wire network bus... (LAN).  Therefore, you can  have multiple sensors and only use 1 arduino signalling pin.

Take a look at Rik's blog here:
http://rik94566.wordpress.com/2012/04/06/ds18b20-external-power-5-probes-working/

He goes through the whole process of setting up and using multiple temperature sensors with Arduino, lots of code examples etc..

Also some How-To here:  http://arduino-info.wikispaces.com/Brick-Temperature-DS18B20 
At the bottom you will also see a waterproof version of the same sensor.
