I guess that it is because of knowledge. I guess that a lot of humans will also fail to see that b6 is winning in a correspondence game when they cannot use a computer. The problem is that when they analyze b6 Nxe4+ Kh4 Nd6 they will think that it cannot be a win for white because after b7 Kc7 is an obvious draw even without the knight and without b7 white has no way to prevent Ne7 Nd5 Nxb6. The failure in this thinking is that the knight e7 is a trojan horse after Ne7 b7 Kc7 d6+ Uri
