I'm not sure I get the point? It was an aural alert that EASA required as part of the SAR AFCS certification. It makes sens in that context and is not out of place in a non-SAR context too. It doesn't differentiate between modes deselcted by button pushing or those that have been forced out for other reasons - low IAS, system faults etc.
