Oh yeah, by this definition interpreted Python is also native like. Just do all your UI rendering by native libs and use scripting to glue it together. But this is not what most of programmers call native speed.
I think you're misinterpreting the meaning of 'native' in this context; the tradeoff in question isn't one of interpreted/JIT'd v. ahead of time to the metal, but rather one of Web v. every platform's standard graphical application stack(s) (which may or may not be ahead of time compiled).
Hence the context of being magical. It is more of a sleight of hand trick than actual supernatural. The author of the post is misusing a development term to convey a different meaning.
