Well, if you look reeeaaal close, the further leg is a little forward, for weight distribution, by the looks of it. However, I did do a little research into this.
I'm pretty light, so what I tried to do is simulate a slog (yeah I'm... wierd like that). I did this by bending my legs till I was short, then stuck the rest of my body forward, so it was similar to the way a slog stands. Also, think of doing a big bow. Their bodies are built for that stance, so maybe they can do it better. Also, I'll try get a slightly less fuzzley picture than that (AO on PC is good for makin' screenies ^^)
