No. All that waffle will not change the facts:
In order for it to be empty, we do not need anything _other than_ for no element to be in it. 
This holds also for the endsegments themselves.

The intersection is a term for every definable n:
∀k ∈ ℕ_def: |∩{E(1), E(2), ..., E(k)}| =  ℵ₀
If you disagree find a counterexample.
