Alternately had they checked the mode first, as they must in Airbus then they would have corrected it then and there knowing that it (OP DES) won't maintain the speed. In Airbus you are not to assume anything as happening unless you confirm the FMA. If FMA was correct and yet speed starts falling that can be confusing. But that wasn't the case here. They committed first error of not getting into correct mode and checking it on the FMA, then committed the second, confirmatory error as it were to not monitor the parameter, the speed to cause the disaster.
and the third error- not disconnecting the automation early enough when it wasn’t doing what it needed to be doing.
