Question 138: Scooping blocks

I am a 65 year old man who has found out the most TKD classes are geared to younger folks.  I have no instructor but practice the patterns because they are good exercise as well as a good memory tool.  I really enjoy doing them and hope I am improving my performance. So you are my only hope to resolve this issue

I am confused about the function of the moves 32, 34, 35, and 36, which are called either scoop blocks or Walking Stance Forearm Circular Block. One technique to do it is to bend down on the back leg like you are blocking a kick and redirecting the kick. Another technique is I have seen is to just scoop it with the blocking hand.

Is the function of this move to block a low kick or to block a punch? Do you need to bend down on the back leg to perform it correctly?
