It is mainly for link building. From experience I know that it is a good idea to create multiple accounts if you are going to put a lot of links on one site. That way if you get an account banned you don't lose all your links. And if you have multiple IP addresses as well it makes it even harder from them to get rid of your links or ban you completely.
Also, today I tried to create multiple accounts on a particular website and it redirected me to my first account when I did.
Thanks for the recommendation - I will try it!
