how to align inside or outside for single pen tool line

[recepgulgun]

As you can see below, I am unable to change the alignment of a single line, made with the pen tool, to outside or inside.

It is possible with the other three figures, these are also made with the pen tool?

Is there any way to get this fixed for a single line?

Answer the question: Where is the outside or inside of that line? 

There is only the line, it has no inside or outside.

Sure, but it could be used to align a left/right line stroke without having to change its location.

Thanx @Pšenda and @Old Bruce for your answers.

My question was actually also related to a question I had previously asked:

So I am actually looking for a way to draw borders of countries without covering the color border of another country.

It would be great if I could draw border lines with multiple colors.

I've also read the link:

So I understand that it is currently only possible if the stroke is closed.

Currently I have come out as follows:

I will experiment with this now Thanks again for all of your help.
