I'm not sure why that thread was locked but when I saw that a long time ago, I showed it to a friend of mine and it turns out that both anime copied those moves. It's a borrowed scene from Bruce Lee, from one of his movies. I don't know which. Just wanted to let anyone who still cares know. And if this is considered a repeat topic or whatever, then sorry.
Yes it was locked, due to off-topicness and a sharp decline in relevance, accompanied by a swift increase in idiocy. Your post has been merged with the thread in question and it is now re-opened on my optimistic hopes that people can actually conduct themselves like decent human beings this time around...
