At authorization stage FreeRADIUS calculates and sends proper Session-Timeout attribute to Access Server that tells him how long user can stay online. This calculations done using attributes such as Login-Time, Expiration, Session-Timeout and current time. If user's time is over limit but he still is online then you can't kick him offline through FreeRADIUS. Because actualy kicking user offline is ability of Access Server not of FreeRADIUS.
