The earlier set of IP addresses was pretty conclusively not North Korea. The new set of IP addresses is ... undisclosed, so until that changes, they can say whatever they like without any "danger" of being checked. (Not buying "sources and methods" as a reason for failure to disclose in this case -- I may not know what IP addresses are conclusively tied to North Korea, but the North Koreans themselves certainly do, and they must assume that the NSA does as well. Particularly if, as Comey claims, the use of those addresses "unshielded" was an error that they immediately recognized as such, and rectified post haste.)
