No, sorry but it won't. Product updates for corp edition are not posted to LiveUpdate.
Corporates deploy in several ways, via ClientRemote, logon scripts, Active Directory deployment or another client management tool (SMS, Tivoli, etc.)
Not sure what you mean by the "main 10.2 package" this update is an addition to the currently released 10.2 package. If we release a maintenance release of 10.2 at a later date, then yes it will be included in that.
