My question was "would natural hyperpolyglot be better capable of learning/using programming languages", and I don't think any of what you said tells us one way or the other. Yes, the things being expressed with programming languages are different from the things being expressed with natural languages, but they are both designed for expression and communicating meaning. I'd love to see studies on whether there's any relationship between being able to easily pick up and retain human languages, and the same for programming languages.
edit: note, that I'm not even asking if someone with an aptitude for human languages would be good at using programming languages. Obviously the logical components, required for doing a lot of things with them, are a completely separate skill.
I'm only wondering if he'd have an aptitude for learning a language, in terms of syntax, grammar, standard library and associated methods, idioms.
