That's correct. After a redirection via X-Accel-Redirect to an
URI, the request method is changed to GET, much like it happens
after error_page redirections (see http://nginx.org/r/error_page).
If you want to preserve the original request method, use
a redirection to a named location.

This might work previously with old nginx versions, as previously
there was a bug which preserved original request method string
representation after X-Accel-Redirect. The bug was fixed in nginx
1.9.10:

*) Bugfix: proxying used the HTTP method of the original request after
an "X-Accel-Redirect" redirection.

This also affects the $request_method variable value you use.
