CCV Hose leading to Oil Pan Return Tube???!??!?!??

[Spanker]

I'm in the process of changing my CCV on my 2002 4.4i. I see there is an extra nipple on the elbow of the CCV facing towards the front of the engine. It looks as though it routes under the intake manifold.

Does this hook up to the oil return pipe leading the oil pan? If so, why do they have two oil return pipes....One leading from the bottom of the oil separator and another leading from the CCV nipple. This make no sense to me...
