The design of disk partition layout is highly dependent on the demands of the system and the file system(s) applied to the device. If there are lots of users, then it is advised to have on a separate partition which will increase security and make backups and other types of maintenance easier. If Gentoo is being installed to perform as a mail server, then should be a separate partition as all mails are stored inside the  directory. Game servers may have a separate partition since most gaming server software is installed therein. The reason for these recommendations is similar to the directory: security, backups, and maintenance.
