 new_acc[i, update_y0 + j] = local_dist + new_acc[i, update_y0 - 1]
 new_len_acc[i, update_y0 + j] = 1 + new_len_acc[i, update_y0 - 1]

are possibly missing a j index on the right hand side of the update rule:

 new_acc[i, update_y0 + j] = local_dist + new_acc[i, update_y0 - 1 + j]
 new_len_acc[i, update_y0 + j] = 1 + new_len_acc[i, update_y0 - 1 + j]
