It does seem to be, doesn't it? It's very unusual for someone who isn't a dancer to have that kind of turnout — that first picture that you posted, with Richard Wilson, is amazing, how easily he's a full 180˚ with his hip completely turned out, it looks as far as I can tell with that jacket on. I can't access the second picture, but I started noticing it in this famous hologram picture, and also when he's standing with his arms crossed in the corridor in "Bad Wolf". (Former dancer, now teacher, occupational hazard!)
