The brifter only defines the amount of cable moved with each shift and how many shifts are available. The rear derailleur responds depending on it's geometry.
Within Shimano's or Campy's various lines the brifters and rear derailleurs are consistent and can be used interchangeably. That is not true if you cross-mix manufacturers components unless you add an adapter (Jtek's Shiftmate is the usual one) to dial out the differences. I have one bike with Campy Ergo 10-speed brifters and a 9-speed Shimano cassette and 105 rear derailleur and, with the proper Shiftmate it works extremely well.
Sometimes,fortuitously, you can mix and match brifters, cassettes and rear derailleurs across various manufacturers and have the bike shift well enough but it's not always predictable.
