IabHelper: disconnection from the billing service is strangely handled

Actually IabHelper contains method to handle it

  mServiceConn = new ServiceConnection() {
            @Override
            public void onServiceDisconnected(ComponentName name) {
                logDebug("Billing service disconnected.");
                mService = null;
            }

            @Override
            public void onServiceConnected(ComponentName name, IBinder service) {
                logDebug("Billing service connected.");
                mService = getServiceFromBinder(service);
                componentName = name;
                String packageName = mContext.getPackageName();
                try {
...

and inside it mService it set to null.

But mService is a widely used field. There are several async methods that use 
mService.  And there is no synchronization, no null-checking.
Could you please explain why it was made so? 
I have this question due to a lot of npe reports from my users. I'm not sure 
that mService became null after disconnect but there is a possibility of it.
