Can someone explain Campy's "S2" feature?

The literature is typical Campy vague, so I have no idea what to make of this:

S2 System (Secure Shifting System):
the special support system built into the derailleur safeguards working of the drivetrain, guaranteeing maximum compatibility with frames on the market.

For brazeon front ders, with brazeon tabs that aren't particularly stiff, this little gizmo that sits against the seattube to make the front der 'stiffer'. Much like the wee post on shimano's front ders and the little supplied plate.

From the link you posted, looks like it just a doohickey that prevents the front derailleur (with a braze on mount) from hitting the frame (a secondary set-screw?)

edit: see OP's post
