leGENdary kiryu left the following in the video description (slightly nsfw);
“Gen’s s.MK, EX Hands loop terror continues in AE, but now vs some new opponents. Who are they you ask? Well.. Yang, Yun, Oni and Evil Ryu.
In Super, Capom originally removed the s.MK, Hands loop that was possible in Vanilla. But after researching and finding new technology, Gen players found that s.MK, EX Hands, s.MK, HP Hands worked on a few characters. Now it’s possible vs the new AE characters. So get that extra damage in and win some matches”
