There is no decrease, they are all infinite.

That is called decrease.

 More like the subset relation. It is not a decrease in cardinality.

Of course not. Cardinality is nothing else than infinitely many.
But as long as infinitely many natnumbers have not left the endsegments, they stay inside all of them. And many are the same for all endsegments. Therefore the intersection of infinite endsegments is infinite.
