Are its knees backwards?

... looks an awful lot like Boston Dynamic's Spot, replete with those backward knees

I believe that in their effort to make Spot vaguely dog-like they forgot to give it knees at all. The thing about dogs (and cats and other 4 legged animals) is a lot of people think their knees are backwards, but in fact the prominent joint is the equivalent of an ankle in a human. AFAIK all land mammals have their knees in the same orientation as humans. Obviously seals and cetacea are built a bit differently, but I understand some of them also have vestigial leg bones in the same orientation but don't have hips so they are disconnected from the spine and thus useless as limbs.
