Why it is recommended to register registerUserNotificationSettings before registering using the push notification service

Question

I was going to use the new iOS 8 remote notification API when I found this in the docs:

"It is recommended that you use this method before you plan local notifications or register with the push notification service."

I could not understand why this is so. I get the impression that two methods are calling:

registerUserNotificationSettings

and

registerForRemoteNotifications

are now independent, while others are not functioning. Then why is it recommended to call one by one?

if (IS_OS_8_OR_LATER) {

        //Right, that is the point
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge
                                                                                             |UIRemoteNotificationTypeSound
                                                                                             |UIRemoteNotificationTypeAlert) categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    }else{
        // Register for push notifications
        [application registerForRemoteNotificationTypes:
         UIRemoteNotificationTypeBadge |
         UIRemoteNotificationTypeAlert |
         UIRemoteNotificationTypeSound];
    }
