Google Play Game Services BaseGameUtils bug

I made an Android project in which I'd like to use GPGS. I set up the project, made some achievements. I use the BaseGameUtils library as a base. At the start, the application asks for which account I'd like to use, and everything is going well. I could open the Achievements activity with this code:

if (gameHelper.isSignedIn()) {
    startActivityForResult(Games.Achievements.getAchievementsIntent(gameHelper.getApiClient()), 101);
} else if (!gameHelper.isConnecting()) {
    loginGPGS();
}

However if I'm there, and I open the options menu in that activity and sign out, and I'm trying to open the achievements again, my application crashes with a message about I should log in before trying to get them. And while this is true, I assumed the gameHelper.isSignedIn() should only return true, if the user is logged in. Is the BaseGameUtils broken, or am I missing something?

Solution

This is the exact issue brought up on the Github issue tracker. The final response was:

This is actually not a bug - it's working as intended.

When you start a GPGS activity, you have to start it with startActivityForResult. If the user clicks on sign-out, the GoogleApiClient is NOT disconnected - it's just in a "signed out" state. The onActivityResult here will return a status RECONNECT_REQUIRED. At this point, the developer should reconnect their client, and life goes on as expected.
