Anabolics 2002 says one thing, then posts another in a forum

In Anabolics 2002, listed under the drug profiles for each drug, the author says that Nolvadex is to be used for anti estrogen conversion . He says that Clomid is used for post cycle recovery along with HCG to get the testes working again.

Then here at this link : http://www.bodybuilding.com/fun/par25.htm
he says some thing different. I have confidence in his later statement
Why didnt he say that in the book? Any ideas ?
Is this a new discovery ?
I ordered The new book, Anabolics 2004. Im anxious to see if he adresses this radical change in his review of nolvadex verses clomid for post cycle recovery .
