No. You're question is like asking "Do you acknowledge that there are some people that are *JUST* taller than 5 feet or shorter than 5 feet, and that there are some people who *JUST* weigh more than 100lbs or less than 100lbs?" You're talking about two different things.
		
		
	 
Obviously physical properties such as height or weight have a truth value regardless of whether someone thinks about them or whether we ask someone about them.
However, you do not know 
unless you have some uncanny ability at a glance what someone weighs and exactly how tall they are. Yes there are ways of finding out about their height or weight with tools for measuring.
Garth, you seem to be pre-occupied with the law of excluded middle. Which if properly applied in this case means you know that a person will have a height greater than or less than 5 feet AND that they have a weight greater than or less than 100lb. This is knowing 
all possible properties. This does not mean you know the 
actual properties. (Or the measured properties if that makes more sense to you.)
Remarking that someone is an atheist or theist (with no hint of whether they are agnostic or gnostic) 
is descriptive. So is remarking that a person is an agnostic or gnostic (with no hint of whether they are an atheist or theist).
Now if you ask them whether or not they are gnostic or agnostic, then they could answer they are undecided. There is no default there, is there?
Now if you are content to browbeat the person into answering yes or no, then obviously there are only two possible answers they can give.
In practice, we don't really browbeat people into answering (I would hope). Because sometimes a person will just give a meaningless answer so the browbeating stops. We instead accept that there is such a thing as being undecided.
This does not violate the law of excluded middle, there are still only two possibilities. We are just making the additional claim that someone lacks knowledge of their own (or of another's) belief state/system.
When someone asks "Are you an X?" or "Is he an X?" The answer "I don't know, or he is undecided." is certainly one we understand. Or would you claim absurdly that we do not know what that means?
Or in your height/weight example: "Is he over 5 feet tall and over 100lbs?" The answer "Yes he's over 100lbs, but that's all I know. I'm not sure how tall he is (he could just be 4'11")" Just as someone could describe someone as atheist or theist without knowing if they are agnostic or gnostic or as an agnostic or gnostic without knowing if they are an atheist or theist. It is a description that we understand.
	
	
		
		
			EVERYBODY either believes in God or they do not. EVERYBODY believes their position to be justifiably known, or they do not.
		
		
	 
Until you 
ask someone or somehow 
read their mind it is an unknown, they are undecided as far as you can be concerned. Are you denying there is such a thing as an unknown? Everbody CAN either believe in God or not. Everybody CAN believe that their position is justifiable known or not. 
Possibility alone does not dictate what they know or do not know of their beliefs, only what their possible beliefs could be.
It is comprehensible to identify oneself as just a theist or atheist.
We know they mean "I don't know if I have the beliefs that make me an agnostic, or gnostic." Of course it's only going to be one or other, but it's also going to be either they know or they do not know and they are asserting they do not know. That is the essence of "undecided".

Let P stand for the proposition "God exists" (or "Whether God exists is knowable" if you prefer)
Let R stand for the proposition I know I have the belief that P. (or ~P if you prefer)
Given a person, they can believe either that P or ~P.
You can browbeat them into answering, but if you do so you are disregarding the dichotomy they are presenting to you.
Given this person, they believe either that R or ~R.
You don't have to browbeat them here, they are asserting ~R.
I am not saying there is no answer to P or  ~P for this person. There is! But they don't know it.
