about pose_NMS error

I think the description of pose_NMS in the paper is wrong, d(Pi, Pj|Λ, λ) ≤ η should be d(Pi, Pj|Λ, λ) > η???
The code seems to support my idea, too! see below,
`delete_ids = np.arange(img_scores.shape[0])[simi > gamma]`

Please give me the correct answer, thanks very much!
