Captain, who did the traslation, is my freind and has wide experience around the world, so could understand and translate some phrases to controller despite of that fact that vocability was pretty unclear
However, having said, that once there is a potential dual engine failure and actual weather (do not rely to the information passed by controller, he was completely lost by that period of time, RVR was 300m) is pretty bad so no chance to survive "landing to Hudson" but to commence an immediate LVP approach to RW.
Also, do not complain the controller too much: they have their SOP which are very unfreindly and have penalties for any deviation from the SOP, and not all the situations (for sure) are detaily documented there, so the purpose of the ATC SOP is rather to cover their boss as$ and punish the controller, than to have documented procedures and governance for emergency and abnormal situations
