A question about corners' calculation

[kaiopen]

In datagen.py:

def get_corners(self, bbox):
        w, h, l, y, z, x, yaw = bbox[8:15]
        y = -y

the bbox[8] is width, bbox[9] is height and bbox[10] is length. But in KITTI's instruction (readme.txt in devkit_object.zip), bbox[8] is height, bbox[9] is width and bbox[10] is length.
