I agree with Joćo's conclusion. After the two pourings, the amount of
coffee in mug1 is the same as the amount of milk in mug2. It follows
also that the amount of milk in mug1 is the same as the amount of coffee
in mug2.
While not a proof, the easiest way to see this is to try simple cases.
Suppose both mugs have 1 tsp of liquid. When you pour all the milk from
mug2 to mug1, mug1 now has a 50-50 mixture. When half of that is returned
to mug2, both mugs have a 50-50 mixture.
Suppose both mugs have 2 tsp of liquid. After the first pouring, mug1 has
2 tsp coffee, 1 tsp milk, and mug2 has only 1 tsp milk. After the second
pouring, mug1 has 4/3 tsp coffee and 2/3 tsp milk, while mug2 has 2/3 tsp
coffee and 4/3 tsp milk.
