I think that's very usefull (expect further descent). This allows me (us) to put the level off arrow approximately 10 miles beyond my (our) current position thus allowing for a continuous descent or at least an almost-continuous one. It's all about style! (displaying [good] style enhances safety, economy, puntuality and pax comfort)
Now don't forget to mention the ATIS
and the runway
and the QNH in your next transmission.
