In my reading of this, it appears to apply (in this case) only to obtaining the IP address of the computer, as that is the information in question. To wit, the user was trying to hide his IP address using TOR, and the FBI discovered his IP address with a hack they call a "network investigative technique" or NIT. Nothing I see talks about the contents of the computer, so in the real world this would be the equivalent of the police tailing you after a crime to find out your home address so they can subsequently get a warrant to search said property. If it's truly this limited, than I don't have a problem with it.
