proxy_request_buffering says nothing about chunks being sent to the
back-end.

You haven't explicitly reported any behaviour that contradicts this quote.

If you report that nginx starts to send the content to the back-end
before nginx has received all of the content from the client, then
proxy_request_buffering is not working as intended.

When I try a quick test here, nginx receives the full content from the
client before it tries to connect to the back-end.
