Well, you have everything positioned right but unfortunately you’ve reached a point in which AE creates those bugs because you have a lot of 3d layers stacked in the same composition.
You have to keep in mind that After Effects is a compositing application and not a 3D one. You should consider going for other easier options.
With that said you still may be able to solve the rendering problems (to some extent) if you keep hiding the faces that should not be seen (like you’re trying to do with that expression). So lets go at that again! Open the same project you sent and select your layer #86. You will be able to see that the face is invisible to your camera while it should not be. Rotate it 180º in the Y axis. Now do you see it? You should, because It now has its “normals” properly aligned, making the expression work as its supposed to.
The bad news is that you’ll have a really hard time changing this to every “reversed” layer, since you already changed their anchor point’s positions.

Are the faces EVER visible and turn invisible when you’re seeing them from the same side?
I know the faces become invisible when you rotate the camera, thats what the expression you applied to opacity is set to do (set opacity to 0 when seen from behind).
The problem is that the faces that should be visible and aren’t, are just probably misoriented or its a problem with multiple composition’s nesting. If the latter is the case, I’m not sure you can solve it.
If you are able to share the project or some extent of it I can take a look.

Regarding your first screenshot, perhaps you have some faces improperly aligned. Are you sure everything is centered?
On the second, I think you only need to rotate the invisible faces 180 degrees on the X or Y axis.

[Alex Cullen] “Im trying to make a flat 2d flag that waves uniformly”
have you tried the wave warp effect?

Have you tried adding a texture similar to that to the normal map?
If you have a proper mesh with uvw you should have little trouble adding some depth marks to it via the normal/bump channel map.

Yeah, you’re right. It only works if you’re wiping from the center (so scale won’t matter).
I think things get pretty complicated if we’re to take into account all transformations with an offset in position. I wish I had the time to figure it out because I’m sure is just a matter of time until I need that too.

I got puzzled by your question so I put this up now, try to use it on the “Wipe Center” property.
a=comp("MAIN").layer("PRECOMP");
c=comp("MAIN");
b=a.toComp(a.anchorPoint);
sum=[(c.width/2)-b[0],((c.height/2)-b[1])];
adjW=c.width/a.width;
adjH=c.height/a.height;

IF you duplicate your base layer and screen it over. Is it closer to what you expect?

Disabling is a very wide concept in AE. You could want to delete, unlink, make them have no effect etc.
Now I see you wanted to just toogle video OFF.
Unfortunately I’m unaware of any automated way to do that just for nulls.

What do you mean by “disable”. And why would you want that?
