That is very first time I am ever hearing this. I have raced back in the days in elite 3 category and at the time being people who used DA 7410 and DA 7700 dual pivot brakes never changed for brake calipers from Campy. Also the Dura Ace brake pads on Shimano were much better than the ones on Veloce or even Daytona. In 1990 braking performance also received attention and the newly introduced BR-7403 Dual-Pivot brake calipers made an immediate impression with their stopping power. Dual Pivot calipers were also extremely easy to centre and they maintained their central position – something that always affected standard side pull calipers. Even the pro teams back in the pro peloton never changed their Dura Ace brake calipers for Campy ones. A review of SHIMANO DURA-ACE BR-7700 BRAKE CALIPERS which were very good , the 7800 were even better .My Mrs' early 70s French mixte has dual pivot Weinmann brakes so the idea that Shimano invented that type of brake is a fantasy. The innovation from Shimano on things like indexing aren't to be ignored but lets not get carried away, eh? A quick google suggests Altenburger were first to dual pivots in the 1960s.
Also the effectiveness of brakes is a highly subjective matter - but I can't recall anyone ever saying there was some discernable advantage to Shimano dual pivots over Campagnolo. I was racing in the early 00s and used both DA and various Campagnolo brakes (Veloce and Daytona dual pivots). If anything it was the other way round. Plenty of crit racers with Shimano gruppos swapped out their calipers for Veloce, believe it or not - because the feeling was they were stiffer brakes.

Ha! I guess they mustI wonder if the neutral service vehicles carry Campag wheels just for Cofidis.
