Yeah that may be, I jsut figured leg kicks were allowed as it appears to be international competition where low kicks are usually allowed. If leg kicks WERENT allowed than nothing wrong with vitali's stance. That's a good way to go if you don't need to worry about leg kicks or takedowns.
He's definitely more of a puncher but good lead leg body kicks.
