Who wins?

It seems only the 50-move rule can save white.  However, starting at this
position:

r1bqkb1r/1ppppp1B/6pp/8/6K1/1P2P3/P1PP1pPP/n3n1RR , White to Move.

Black's last might have been 0...g7-g6.  Now, I reach the initial position
via:

1. Bg8 Bg7 2. Bh7 Bc3 3. Bg8 Kf8 4. Bh7 Kg7 5. Bg8 Kf6 6. Bh7 Ke6 7. Bg8
Kd5 8. Bh7 Kc5 9. Bg8 Kb4 10. Bh7 Ka3 11. Bg8 Kb2 12. Bh7 Kc1 13. Bg8 Kd1
14. Bh7 Ke2 15. Bg8 Nd3 16. Rb1 Nb2 17. Rhc1 Nd1 18. Bh7 Kf1 19. Kf3 Kg1
20. Ke2 Kh1 21. Kf1 Nb2 22. Bg8 Nd3 23. Ke2+ Ne1 24. Kd1 Nf3 25. Rb2 Kg1
26. Rcb1 Kf1 27. Kc1 Ke1 28. Bh7 Qf8 29. Bg8 Qg7 30. Bh7 Qd4 31. Bg8 Qc4
32. Bh7 Qf1 33. Bg8 Qh1 34. Bh7 Kf1 35. Bg8 Kg1 36. Kd1 Nd4 37. Bh7 Nf5
38. Bg8 Ng3 39. Rc1 Nf1 40. Ke2 Bd4 41. Re1 Bc3 42. Kd1 Be5 43. Re2 Ng3
44. Bh7 Ne4 45. Bg8 Nc5 46. Bh7 Na6 47. Bg8 Nb8

Which is 3 full moves short.  It seems white is lost, but surely this cannot
be the intention.
