The article I linked says that the _paper_ that TFA refers to[0] says nothing about a reversal of the current, only a reversal of the freshening of surface water on the polar southern ocean. Is that not indeed a correct reading of the underlying paper? That's a simple yes or no question. See for yourself[0]!
