Nope, not wrong. This is a pattern recommend by MS.
It looks wrong because the client is disposed immediately after the asynchronous call, and most probably before the callback has been processed. Internally, the service client uses a channel object from a pool of channels. So disposing the client means releasing the channel to pool and the pool or channel itself maintains the state of the call.
