This is really all about anthropomorphisation.  There's not much
detail on this robot, so I would guess that it's ability to detect
body postures of humans is just something hard coded into the system
(I've tried doing this myself, and it does work to some extent).

However, if you're going to do this properly with the system learning
autonomously initially it just needs to experiment with its own body
(play) and construct a theory of itself and how it moves, similar to
the Cornell "starfish"
(http://ccsl.mae.cornell.edu/research/selfmodels/morepictures.htm).
This "theory of body" can then be mapped onto patterns of optical flow
observed whilst interacting with other people (a kind of mirror
system).  In this way even with quite minimal or noisy visual
information the system is able to robustly estimate body postures.

The interesting side effect of this is sometimes the system makes
plausible mistakes by superimposing the model onto creatures or
objects with a non-anthropomorphic body layout.  As humans we do this
all the time.
