What can't you understand here?
{E(i):i} is the set.of.all non.empty end.segments.

∀n ∈ ℕ:
{E(i):i}∪{E(n+1)} = {E(i):i}
Each is "already" in.
Not the empty endsegment.
∀n ∈ ℕ: E(n) is non-empty. But not every E(n+1).
You could hardly write something worse and more wrong that that.

The very core property of N is that if n ∈ ℕ then n+1 ∈ ℕ.
That is correct for definable natural numbers and even for almost all dark natural numbers.

The very core property of analysis is that equal sequences have equal limits if they have limits at all.
Lim E(1)∩E(2)∩...∩E(n) = {}
Lim E(n) = {}
The are equal.
