It's actually pretty simple and several VPNs have explained how they do it. You connect to a server, when you connect with a different device that server checks with the other server to see if the same login credentials are also connected. If the provider has lots of servers like many of them do, they report to a single server designated to the task. Once you disconnect your devices the account is no longer propagated to the servers. There is no need to retain any trace of your connection past the point of disconnection. Logging entails storage of personally identifying information beyond disconnection, which these providers claim not to do.
