Yes, and besides the above mentioend "basic principles" mentioned in chapter 20 "law ethics, religion and BM" of the textbook "Basics of Blood Management" there is a distinct chapter called "Jehovah's witnesses" included, simply the quote "J.W. love and cherish life", shows that this was a part written by J.W. HLC members, nobody else would write such a text.
It is therefore evidently that these parts of the scientic textbook were written mainly with the group of patients in mind which is mostly concerned - j.w. It shall be a helpf for doctors and nurses to better information about Jehovas witnesses. (?) These chapters are therefore of informational character. The inaccuracies could be inaccidently because nobody would be interested in awkward embarrasing details anyway, perhaps even neither HLC nor the authors were informed about those details about these persons you mention and they were not historians, or the HLC didnt support the two authors with accurate informations.
Concering Prof. Shander, I watched some videos with him he is a man who believes in a mission, he is a fighter against big resistance, he believes that he has a mission and that truth will vindicate in the end. (I will write later more about). It looks even like he was a J.W., how he talks and how he acts, the HLC may have influenced him and supported him in his mission, so he is now in an oneway of "missionary" combat.
I dont think that the WHO is accountable for the context of these books are has even read the content.
