In that picture, it doesn't.  As noted in my earlier post, on the 1.9D engine w/ rotary vacuum pump, there is no vent line on 
the pump like there is on the diaphram sytle pump.  So that part of the plumbing is missing, so the line runs from the crankcase 
to the valve cover where it connects into the line running to the intake.  The idea is to tie all the vent lines together.  VW 
used to sell a fancy hose kit to do that; basically crankcase vent to pump vent to valve cover vent to intake.
