Regarding "update" versus "upgrade", I'd like to give reference to
this forum thread:
http://www.centos.org/modules/newbb/viewtopic.php?viewmode=flat&topic_id=16315&forum=27
It boils down to Seth Vidal's own words,
"upgrade/update do the same thing unless you've gone out of your way
to disable obsoletes in your yum.conf"
and who else can say more about yum than Mr. Vidal? :-D
