I have noticed that the personalized status is missing the enabling time as it was in the earlier versions. For example: When I change my status to AWAY personalized status window used to ask after how much time you want to enable personalized status. It is not there anymore. What happens is, if messenger/internet disconnects and your personalized status was "sleeping" it will auto sign in again when the connection is recovered but with an online status when you are sleeping. So in case of a disconnection the personalized timer helps, like if messenger reconnects after a minute or couple of seconds your status stays as it was selected before disconnecting. It happened as I left my status "Sleeping" and after the messenger connected ..my status remained ONLINE!!!!
