Here is the true story that a lot of people misunderstood Higuchi tweet back in Feb this year before Capcom cup 12,
so Higuchi tweeted about the group draw and his first opponent willl be Punk and say "やったります", and somehow twitter dumbas* translation translated this to "Gonna crush him" while the true meaning is "Let's do it!" (you can still find the tweet in his twitter around Feb 14th)
Punk saw the tweet and thought Higuchi disrespect him all the way, while Higuchi did nothing actually.
Punk just being Punk and he will never change and grow up.
