Well according to GIB 2NT is the strong answer to a weak 2, so the explanation is correct, but West (BEN) was bluffing :-)
Over 2N North did not have the HCP for bidding 6♣ as it would show 32+ total points, and settled for 5C. After the double GIB has the same explanation for both Pass and 6C, so BEN probably picked up somewhere that with 12 tricks it is a good idea to bid the slam.
But a really nice hand.
