are the ha say fu five animals forms the same as the traditional shaolin five animals? characteristics of each? differences? the same?

also, are the fundamental open-palm blocks done when and only when you are facing your opponent? it makes sense that it would be this way, because the opposite hand is positioned to protect the torso. and it is this way, are the closed-hand blocks done from the side (horse stance)?

please elaborate if you can on either or both of these questions. it would be greatly appreciated.
