I noticed the same system in the Google Cloud python samples repository. It's actually quite useful to have the full code available and to easily see which parts are displayed in docs. Feature request, though: include a url in the source code that takes you to the snippet's usages in documentation. Something like // [START https://codesamples.google/firebase/set_document https://codesamples.google/firebase/set_document ] or just the url as a separate comment.
