The block is an entire HTTP transaction. There are (likely) multiple transactions in the report.
Your browser sends everything in the first part of the first block to your server as an HTTP Request. One line of that request is the GET request, asking for the specific page.
In the second part of the first block is the HTTP headers that the website sent back. If that response contains a redirect code (301, 302, 307) you will see that clearly in the response.
The browser will then make a new request for that new URL. This will appear in the first part of the second block.
The server response will follow that in the second part of the second block.
Scroll up and down to see all of the transactions.
