I was watching an “elite” Yun stream just now, 16th or 17th ranked player on xbl, and I had the input display turned on so I could study what power of attacks (light, medium etc.) he was using for his specials. I noticed that, every time he started his bread n butter combo with crouching lk (cr. lk. X3 xx Choppy hands X3), the input display would show that he was hitting lk and lp simultaneously for each of the initial 3 lk.'s, even though it appeared all he needed was the cr. lk presses.
My question is, was there a purpose to this, some kind of option-select, maybe, or was it just a quirk of an individual player mashing unnecessary buttons?
