Bordered Chevron Steps 4-7 Question

In steps 4 through 7 it goes on about what knots I should be doing on the right but that leave the left (#1) blue strand completely untouched.


Should I be doing each step on the left as well with reversed knots?

For example;

Step 4
Starting on the right and using the blue (#1) strand, make a backward/forward knot. The color position should not have changed

Would I do the same thing on the left only doing a forward/backward knot?

Step 5
Using the orange strand (#2) on the right, make two backward knots.

Would I do the same with two forward knots on the left?

Step 6
On the right and using the blue strand (#1), make a forward/backward knot. The blue should remain on the outside when finished

So would I do a backward/forward knot on the left?

And If I did repeat all the steps on the left with reversed knots would that mess up step 7?

Step 7
Using the orange strand (#2) on the left, make three forward knots, joining the orange strands (still #2) with the final forward knot. The color arrangement should now be: 1342 2431 (blue-taupe-green-orange, orange-green-taupe-blue).

But if I don't repeat all the steps on the left (with appropriate/reversed knots) then what happens to the left blue strand? It is never mentioned till step 9, which is an optional step.
