SCV - Tira move question from jolly stance

I’d ask this at 8wayrun but it looks like they’re down and I’m working on combos so

So I’m watching Urichinan’s video, I can’t seem to get 6+K to turn me into the gloomy stance after I do 66B 4A 4K, I’m still in jolly stance. Is it because of my meter being full? Tira gets a headache it looks like and doesn’t switch
