Yes, the doctor is over 50 years old :-)

Ok, better answer.  A PVR will give you a better idea of the total blood
flow to that limb, ie collaterals and all.  The duplex will specifically
show how the main artery is doing.  Occasionally I have seen a chronic
SFA occlusion with such good collateral flow via the deep femoral and
others, that the PVR waves will look almost normal.

Is there a reason why a Dr. would order  a bilateral arterial duplex and
LPVR on 
the same patient?
