He meant one script per thread.
Each asynchronous function started, starts in separate thread.
So in that example you will have 2 threads since 2 asynchronous functions
will be started, each with its own (different) script.
Hello, I noticed that Get request does not use connected proxy network to request, it uses default network which exposes original IP address.

In this case, after connecting to proxy, I do a GET request to get my ip, instead of getting proxy IP, I get my original IP.
