It is so because addition of first Br requires formation of carbocation intermediate but the benzenonium ion gets stabilized at a fast rate subjected to rearrangement.
Bromination is an aromatic substitution reaction in which bromine is added a an electrophile to the benzene ring through sigma bond further a proton is removed from intermediate to form substituted benzene ring. While further addition of bromine makes the benzene ring less stabilized and hence faster rate of substitution
