Hook = he has never been credited Killian Jones, so that's not the same case here. And contrary to the Snow Queen, even after we know his real name they continue to credit him as Hook. Here, at the time they revealed Ingrid's name, it was add on the press release :)

Actually, in 2x04's press release, he was credited as Killian Jones and then in 2x05, he was credited as his alias  of Captain Hook then Hook.
