I think the programming analog of sight reading might be following along with assembly language or other low-level or simple imperative code while mentally tracking basic stuff like register/variable usage and control flow. Sight reading music doesn't involve real-time analysis of the broader abstract structure of the piece. That's not really applicable to high-level code making heavy use of nested abstractions or non-imperative paradigms.
