C++ Force kick when client close

[Ascuas Funkeln]

    if (noPongTime >= 60000 && canLogout()) {
        if (g_creatureEvents->playerLogout(this)) {
            if (client) {
                client->logout(true, true);
            } else {
                g_game.removeCreature(this, true);
            }
        }
    }

Someone can explain me how this work? Because its not work like i think it should work...
What i need is to make player force kick when they close client, but he can be unlimited afk when client is online.
So, editing time in kickidleplayer is useless in this case.
Change this:

    if (noPongTime >= 60000 && canLogout()) {

to this:

    if (noPongTime >= 60000) {

Make player kick even when client is online, player walk etc. Just wtf?
