It's said here that the witness is noncontradictory if  E X A C T L Y one child sayd it was him, and there was no circle. But it's not true. In test 3 there is more one child who said it was him, and still it was considered noncontradictory.
Actually it sounds like this: "At least one child said it was him and there was no circle"

In fact it's wrong! I've read your message and got WA two times!!! It have to be exactly one child said it was him!
