Your example assumes a nested, hierarchical structure while the former example is strictly linear. IMHO that's the key difference there, as the former can (and AFAIK is) be directly encoded and passed to the LLM, which inherently receives only a flat list of tokens.

Your example might be nicer to edit, but then it would still have to be translated to the actual 'guidance language' which would have to look (and be) flat.
