Besides the fact that his public goodwill and expertise is valuable, Anand has been behind the scenes at many of Apple's competitors.

His extensive knowledge of the competition's 4-year product timeline is well worth whatever extraordinary concessions Apple must have made for him.

Does he have nonpublic knowledge of those product lines?

A 12 year old could tell you what the competition's 4 year product timeline looks like.

No evidence of course, but I'm going to think most people will say his knowledge of hardware (and his connections).

Apple could have big plans for their ARM64 platform. Anand could be part of it.
