cross platform - How does React Native for Windows/macOS/Web etc. work?

Question

There are many GitHub Repositories, that add Support for another Platform to React Native, like
React Native for Windows: https://github.com/microsoft/react-native-windows
React Native for Web: https://github.com/necolas/react-native-web

As far as I know, this enables developers to write just one code for web/windows etc. in addition to iOS and Android.

My question is, how do these repositories work exactly?

Considering the the React Native architecure by Lev Vidrak in this talk: https://www.youtube.com/watch?v=ZwX3i3e1Vfs, my guess is, that these repositories simply add Native Modules for their respective platform, but I haven't been able to find any sources neither confirming nor denying this.

If you can, please include a source in your anwser, thank you!
