UPDATES:

I established a explanation as add against to confusion condition about second procedure.Where;

Lila Colour Step>First movement as East-directed.Thus,I summaried NWestern backward condition of Machine👍

Dark Brown Colour Step>Second movement as West-directed.Thus,I summaried NWestern backward condition of Machine👍

Light Blue Colour Step>Third movement as North-directed.Thus,I summaried W backward condition of Machine👍

Light Brown Colour Step>Fourth movement as South-directed.Thus,I summaried NWestern backward condition of Machine👍
