His opponent is on the east direction. If he needs to generate power on his left-hand strike, he will need to bend his right back leg, borrow the counter force from the ground, and then straight his right back leg. Since his right foot points southwest, that will put extra pressure on his right knee. Of course he can turn his right foot first. But that will add extra time for his left-hand strike.
Every time when I see a posture like this, I just like to ask what's the PRO for this?
