Other than the deflector difference between LHD and RHD I don't think there is a material difference. Low beam is directed through a projector lens (and then through a beam deflector in the front glass. High beam sits in a common or garden reflector arrangement aimed through the front glass. As alluded to by Andrew, the European models have headlight adjustment contols (are they not in US models?), which allow a small manual vertical adjustment to compensate for load - but not enough range (or speed of operation) to look after low and 'high' beam applications.
As I wrote earlier, the beam pattern using xenons on high beam is 'different' because the increased brightness accentuates areas of lens (and therefore the road, and trees and hedges) that would not normally be illuminated enough to notice with halogens. Try it. Buy a set and try them in both positions (easy install) - if you don't like it just keep them in low beam. However, I believe you will see the light, like me, and never go back.....................

Bear in mind the xenon is designed to sit behind a projector lens and is considered illegal in some places if fitted with a reflector because of the risk of 'blinding' oncoming motorists at night. With a reflector setup they can be too bright in certain circumstances.

To my knowledge, not all European models have adjustable head lights. At least in Germany, I think they changed in 97 because the load change in a 993 is not very significant (no trunk in the pack, limited weight on back seats, stiffness of car).
