In my case I am doing as following. On MainActivity ovveride onActivityResult(). RC_UNUSED is the requestCode when you call to open Leaderboards, Achievements and Settings activity from Google Play service app.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);
if (requestCode == RC_UNUSED 
&& resultCode == GamesActivityResultCodes.RESULT_RECONNECT_REQUIRED) {
        signOut();
    }

    Log.i("test", "On Activity result called");
}   

Write your signOut() method as following

public void signOut() {
    try {
        Games.signOut(mGoogleApiClient);
    }catch (SecurityException se){
        Log.i("test", "mGoogleApiClient status was disconnected when callin signOut status. message = " + se.getMessage());
    }
    if (mGoogleApiClient.isConnected()) {
        mGoogleApiClient.disconnect();
    }
    // update your UI logic here (show login btn, hide logout btn).
}

Don't forget to update your UI on the end of signOut()
