The Bak-Hok they were referring to is Northern Bak-Hok,Tibetan White Crane (Lama P'ai) and Hop-Ga, all of which are considered to be White Crane styles. They are not referring to Fukien Bak Hok P'ai.
I also believe that Northern White Crane, and Lama P'ai also have Needle in Cotton set, so now it becomes curious once again.
