The example might be a bit misleading in your case. What X-Accel-Redirect does is take precedence over the location uri. You don't specifically have to pass the location match to a directory for downloads, you might just as well pass it along to another backend.

This is how my setup looks like:
 - incoming get /foo
 - location match on /foo that passes to fcgi backend
 - fcgi backend analyzes request and returns response with x-accel-redirect /backend1/foo
 - location match on /backend1 passes the request along to http backend
 - backend responds with "final" request, master sends back to client
