Well, think of it this way, with those options you are manually triggering an exception which is technically legitimate, and the system sees that and will respond appropriately (like giving the proper bugcheck type for the key-triggered BSOD). There are no alterations done to the environment.
With NotMyFault, however, it is designed to cause corruption in the environment in one way or another, again for training purposes. This corruption will obviously complicate things if you're looking for a problem elsewhere, and may even alter the environment so that you won't find the answer you seek anyways.
