See section 5.3 of the standard (http://www.ietf.org/internet-drafts/draft-ietf-openpgp-rfc2440bis-15.txt). The reason for doing so is mainly that you can specify more than one recipents. The standard would also allow to directly use the s2k-generated key, but I don't know wheter or not gpg support this.
