Yes this decrease produces subsets. All infinite subsets produce 
infinite intersections.

No intersection of infinite endsegments is finite.

Every infinite endsegments has an infinite intersection with all its 
predecessors. If all endsegments are infinite, then this holds for all 
endsegments. They simply had not the chance to lose these numbers.
