The controller uses the aircraft callsign prior to the message because he is talking to a number of aircraft; therefore he nominates which aircraft he is talking to.
When the aircraft replies, there is only one controller so the answer is given first, followed by the callsign.
If the pilot was initiating the message his callsign would go before the message, so that the controller would know which aircraft was talking to him.
see CAP413 Continuation of Communication.
"N8WS,what is your position?" is Incorrect RT; it should be: N8WS Report your position.
Answer (Position- relative to something the controller will understand) N8WS
Words such a "Currently" and "Copied" are not standard phraseology and are examples of poor RT discipline.
