Originally Akira said "looks like a shotokhan stance" but I wasn't sure if there really was a stance like that in shotokhan and I didn't want a shotokhan karateka to chew me out if there wasn't. But I did know that there is a stance like that in wing chun matter of fact I re-learned it a couple months ago thanks to a friend of mine. Though that kick wasn't wing chun, more like Bokator to me.
Also yes, in my family for some reason when we rely on our instinct we seem to instinctively assume a wing chun stance. Well, me and my dad do anyway.
