Actually, for humans this actually is a face recognition task - from the given examples, it seems that the dataset involves pictures of publicly known people, so it's comparing apples and oranges as humans are given an entirely different task.
Computers are given 2 pictures and asked "Are these the same person?"
However, if people are given the same 2 pictures, and one of them is a well-known actor; then the question is "Is the second picture the same person as the many pictures of this actor that I have seen during my life?" which is a rather different task.
If you want a fair comparison, then either you have to use portraits of people that nobody knows, or the computer systems need to use databases of celebrity pictures for that.
