I read this to mean that he has taken steps to limit the specific data he knows. So even if he has or had access to documents, he hasnt tried to memorize anything that could be damaging. Meaning they cant force him to reveal information he "doesn't know"

Can we assume that if he is the part of the secret key then if somebody does something bad with him we will lose all the secret docs?
