I experienced the swing over procedure in EDDF on quiet a few occasions, but to avoid the confusion you can always refuse the swing over in the first place and if you have to do a G/A because of it ,there is no argument!
I'm all for keeping it simple, it's difficult enough to decide if it is tea or coffee on the turn around.
The other thing in EDDL is that they ask you to swing over fairly late, which at the time didn't conform with our SOP, stablised approch criteria.
good luck anyway
