More accurately, it adds an extra IP that changes regularly; you still have the permanent IP that you would have if you didn't enable privacy extensions, but you also have a temporary IP that changes, and that is used in preference to your permanent IP for outgoing connections.
The idea is that if you give me your permanent IP, I can connect to you. If you don't, the only IP of yours I know about is your temporary IP, which changes regularly - so while it's fine for the duration of communication you initiated, it's not useful in a few days time.
