The Notification Center on iPhone is designed to provide a summary of Calls, Messages, Updates and Alerts from various Apps installed on your device.
This practically means that anyone that comes across your unattended device would be able to take a look at your personal Call and Message Notifications.
Hence, it makes sense to Disable Access to Notification Center Access from the Lock Screen of your iPhone and prevent the possibility of your personal Call and Message Notifications from being viewed by others.
