Idiot campag derailleur cable question

I'm about to change my rear derailleur cable (Centaur carbon 2009 ergos), and I've got a new campag cable set. The contents say 6 x casing caps, but I only have 4. the instructions say:
But there are no pre-mounted caps (the two missing ones presumably). And the cables that I've just removed from the ergos had no caps (that I noticed).
So is the documentation incorrect and no caps are required at the ergo end?
Front and rear derailleurs' casings have been pre-lubricated with a special grease, which has been inserted in the half of the casing where there are no "Campagnolo" logos and on which an end-cap has been pre-mounted. This is the end of the casing that must be inserted in the appropriate slot in the Ergopower control level body; if the casing needs to be shortened, the other end (with the double "Campagnolo" logo and without the end-cap) must be cut.
