   buffered in the request body.
   It is imperative that the request body is buffered by a prior middleware
   handler as given in the example above.
-  This previous middleware handler is also responsible for rejecting incoming
-  requests that exceed allowed message sizes (such as big file uploads).
+  This previous middleware handler ignores requests that exceed allowed 
+  message sizes (such as big file uploads). But still passes on the request 
+  once the full body has been transmitted, resulting in an empty body.
   If you use this middleware without buffering first, it will try to parse an
   empty (streaming) body and may thus assume an empty data structure.
