I believe [`incorrect leg anatomy`](/tags/incorrect+leg+anatomy)'s description implies something that doesn't fit entirely with its list of images:
> Missing or reversed joints and other such anatomical errors. Applicable regardless of degree of anthropomorphisation - both horses and humans have same amount of joints in the limbs. For humanoid legs on otherwise quadruped characters, use [semi-anthro](/tags/semi-dash-anthro) instead (and don’t forget to remove [pony](/tags/pony) if it refers to same character)
Through a combination between that definition and what the term looks like: If both hind legs on all onscreen characters bend like a human's, then it should be considered `semi-anthro` instead of `incorrect leg anatomy`, no matter how odd the "forelegs" look (humanoids have arms; not forelegs).
