Personal choice, but if you don't decouple, the AP will level the aircraft and fly it down the runway and the pilot will need to control the speed by lowering the collective....!!
As I already wrote:
The AP is capable of leveling the aircraft at the completion of the ILS but at that stage the airspeed still has to be controlled by the pilot using the collective. It's actually quite unnatural to significantly lower the lever - lowering the lever brings up the nose, rather than the possibly more usual expectation of it causing the nose to drop. If you are still in fog at that stage and not used to it, possibly more than a little disorientating.
