Why would "one" throttle be retarded in an ATR?
It's a memory item action for securing a failed engine, but NOT a fully working engine. The power lever (they're not called throttles btw) is brought to Flight ldle and Condition Level to feather and then to fuel cut-off of the AFFECTED engine.
It's obvious they mis-identified the failed engine and that there was poor CRM, because before making such actions, the PNF who is performing the actions needs to confirm with the PF that the Power Lever and Condition Lever is that of the affected engine, whilst the PF continues to fly the aircraft.
