Yes, you are. For an 850rpm landing, a button is pressed that locks the RPM at that value, but the condition levers are set to max. When a certain power lever angle is exceeded thereafter, the "lock" is opened and the propellers spin up to 1020rpm. This is mostly intended for the go around case, but in very gusty conditions, it might happen inadvertently as well (as Tojo-san referred to). Also when one pushes the power levers beyond the rating detent, the propellers will be automatically set to 1020 regardless of C/L settings in order to avoid an overtorque as long as possible.
