The way they may be damaging the alternator is if they are following some bmw test procedure included in the recall instructions that tries to evaluate cable electrical integrity from alternator to battery B+ by connecting that cable to some test load equipment that temporarily overloads the alternator with engine running. A corroded cable will show increased ohmic drop at high current load. The test could overstress the alternator if some tech is not meticulously following test max load/duration specifications.
It might not be exactly on those lines but somebody is breaking these alternators.
