He means that many programs see that white has an advantage after those moves, even though after Ne5 Be6 Bxe6 fxe6 Nf7+ Ke8 Kxh8 white can be losing. Incidentally, this is what I get here for output on the position after Bxc4 dxc3 Qxd8 Kxd8: 5 1.25 ++ 3. Ne5!! 5 1.45 -1.52 3. Ne5 Nh6 4. Bxh6 Kc7 5. Bf4 cxb2 6. Nxf7+ 5-> 2.02 -1.52 3. Ne5 Nh6 4. Bxh6 Kc7 5. Bf4 cxb2 6. Nxf7+ 6 2.18 ++ 3. Ne5!! 6 3.24 -1.07 3. Ne5 Nh6 4. Bxh6 cxb2 5. Nxf7+ Ke8 6. Rb1 Rg8 6-> 4.44 -1.07 3. Ne5 Nh6 4. Bxh6 cxb2 5. Nxf7+ Ke8 6. Rb1 Rg8 7 6.67 -0.97 3. Ne5 Nh6 4. Bxh6 cxb2 5. Nxf7+ Ke8 6. Rd1 Bg4 7. Rd8+ Ke7 8. Bg5# 7-> 10.19 -0.97 3. Ne5 Nh6 4. Bxh6 cxb2 5. Nxf7+ Ke8 6. Rd1 Bg4 7. Rd8+ Ke7 8. Bg5# 8 12.84 ++ 3. Ne5!! 8 21.69 -0.46 3. Ne5 Nh6 4. Bxh6 gxh6 5. Nxf7+ Kc7 6. Nxh8 Bg7 7. Rc1 Bxh8 8. bxc3 8-> 28.26 -0.46 3. Ne5 Nh6 4. Bxh6 gxh6 5. Nxf7+ Kc7 6. Nxh8 Bg7 7. Rc1 Bxh8 8. bxc3 9 52.80 -- 3. Ne5 9 1:03 -0.90 3. Ne5 Be6 4. Bxe6 fxe6 5. Nf7+ Ke8 6. Nxh8 g6 7. Ke2 Bg7 8. Rb1 Bxh8 9. bxc3 9-> 1:21 -0.90 3. Ne5 Be6 4. Bxe6 fxe6 5. Nf7+ Ke8 6. Nxh8 g6 7. Ke2 Bg7 8. Rb1 Bxh8 9. bxc3 10 1:51 -1.27 3. Ne5 Be6 4. Bxe6 fxe6 5. Nf7+ Ke8 6. Nxh8 g5 7. Bxg5 Bg7 8. bxc3 Bxc3+ 9. Ke2 Bxh8 So it is seeing that white is bad after Nxh8. Instead of Bxc4 it prefers to play Qxd4 with a score very near zero.
