I am going to jump in here with little knowledge.
I just find it interesting that we have two aircraft on a converging course that it requires ATC to require both aircraft to take evasive action.
My first thought would be that ATC should have only needed to vector, change altitude, or slow down one aircraft from the converging course long before the situation degraded to the point of requiring both to evade.
Hence, there would only be one set of instructions.
Again, I do not know.
