Based on my measurements that's not right, Shimano brake cables do have larger heads than Campy's.
I've measured Shimano compatible brake cables and Campy's cables provided with their brifters and gotten the following diameters:
Shimano barrel: 0.238"
Shimano shank: 0.140"
Campy barrel: 0.214"
Campy shank: 0.138"
So, while the shank diameters are nearly equal, the barrels are different enough to cause fit problems unless Campy drills their brake cable stop holes well oversize.
For the record, the shift cable barrel dimensions are:
Shimano: 0.173"
Campy: 0.159"
