You are right, Nick, I understand your point.
The big difference is that "legal" (I mean perfectly normal in the Company point de vue as well) nested ticket is the obvious side trip.
Another exemple : you fly ORY/LCY on wednesday (meeting in London), your return being EDI/CDG on next monday night because you have another meeting there (at EDI). You are on vacation thursday and friday, you fly to AMS, return to EDI sunday evening. I don not see any problem.
A ORY FDF return with a FDF ORY inside sounds funny because it's pretty obvious you screw the rules, but IMHO not illegal.
DL exemple : you fly CDG HNL, two weeks, and want to spend the middle week end at SFO. I suppose DL will not ask any question if you book these two tickets.
