Well, except for the confusing statements about "GET" and "post", it's really not that unorthodox. Simple "page requests" was for a long time the main way for Flash to communicate with backend servers. Actually I think it's still the most commonly used way.
AMF and SOAP have gained popularity lately, but also REST, which kind of shares the conceptual simplicity with the page requests.
