Can you identify the ryu from which this block origianated?

TKD, karate and Okinawa-te tend to be taught from the perspective of position. Even some chinese systems are position based and position is never unimportant, but there is a tradition of martial arts that places more emphasis on flow. The flow systems are really enlightening to someone coming from a position based system.

The problem I see with your inquiry, (I like the question and I'm not being dismissive) is that the question is much bigger. The block does not exist in a vacuum, it comes from a flow from there to here. I never understood the X block until I got involved in Filipino Kali and realized that it wasn't what I thought it was. Any block is loaded from the previous position out of necessity and any competent system is going to be consistent with that. Position based systems obscure the loading principle, but it is there and once you see it classical martial arts start to look a lot more interesting.
