When exactly onServiceConnected for bounded service will be called?

I am trying to bind service from another service like this:

public class ServiceA extends Service {
    private ServiceB mDataService;
    private boolean mIsBound;

    @Override
    public void onCreate(){
        super.onCreate();
        doBindService();
        /* ... */
    }

    @Override
    public void onStart(final Intent intent, final int startId){
        /*...*/
    }

    private ServiceConnection mConnection = new ServiceConnection() {
        public void onServiceConnected(ComponentName className, IBinder service) {            
            mDataService = ((ServiceB.LocalBinder)service).getService();
        }
        public void onServiceDisconnected(ComponentName className) {             
            mDataService = null;
        }
    };

    void doBindService() {          
        bindService(new Intent(ServiceA.this, ServiceB.class), mConnection, Context.BIND_AUTO_CREATE);          
        mIsBound = true;
    }

    void doUnbindService() {
        if (mIsBound) {                     
            unbindService(mConnection);
            mIsBound = false;
        }
    }       
}

This is a simple snippet that I took from goolge's samples :) The code works just fine and mDataService holds a reference to ServiceB instance, but there is one thing I could not understand: the onServiceConnected callback is called after the call to onStart. As I saw on android's docs, the callback is running on the main thread - but can I count on it that it will ALWAYS happen in this order in my case? onCreate -> onStart -> onServiceConnected ?
