Yong Gae Tul Confusion

I am a little confused and would appreciate some clarification with regards to Yong Gae.

I have recently been learning this pattern and have come across some differences with the references that I am using (Official TAGB DVD & Tae Kwon-Do Legacy and also movement palns on Blacbelt Schools.com and ITF movement plans).

Please help:

1st - Movement 38. Move the left foot to D turning counter clockwise to form a left rear foot stance toward C while executing a waist block to C with the right inner forearm (TAGB DVD performer actually does an outer forearm.) Is this just a subtle difference that we perform across the board in the TAGB or is it an oversite from the original form?

2nd - Movemet 41. Move the right foot to D turning clockwise to form a right rear foot stance toward C while executing a waist block to C with the left inner forearm. (TAGB DVD performer actually rotates anti clockwise and again performs an outer forearm block.) Again is this just a subtle difference that we perform across the board in the TAGB or is it an oversite from the original form?

Would much appreciate any assistance with this.

Hi, check with your instructor is the best thing to do. Many thx gaz.
