None at all. Since both containers have the same amount of liquid (call it "a") in the end-result, the amount of impurity (amount of the "other" liquid) - call it "b" must needs also be the same. If one container has (a-b) water and (b) milk, the other must have (a-b) milk and (b) water.

Or, you could make a detailed analysis of the liquids transferred, with three variables: "a" for the volume of liquid in each container, "b" for the volumne of the tablespoon, "c" for the amount of "impurity" in the second move.
