they are imported.

Windows uses winsock:

posix uses their socket thing:

So all the leading dot does is go back to the top level - the 
module - and then if there's a local one defined there, it uses 
it, otherwise it scans the imports like normal to find it.

See my search results:

and you can see where the bindings come from.

So it binds to these functions ultimately:
