Redundant call to showList() method in MainActivity.java

In the onCreate() method of MainActivity.java we have the following code:

if (savedInstanceState == null) {
    showLoading();
    Etsy.getActiveListings(adapter);
} else {
    if (savedInstanceState.containsKey(STATE_ACTIVE_LISTINGS)) {
        adapter.success((ActiveListings) savedInstanceState.getParcelable(STATE_ACTIVE_LISTINGS), null);
        showList(); 
    } else {
        showLoading();
        Etsy.getActiveListings(adapter);
    }
}

The call to showList() above seems to be redundant since inside the success() method of the adapter we have this code: this.activity.showList().

Actually, Jamie Huson removes this method call later in the "Integrating GoogleServicesHelper" section.
