True. Basically, the brine is just sea water with some of the water removed. Based on the numbers in TFA, 2.5L of sea water becomes 1.0L of fresh water and 1.5L of brine. And so the brine is just 67% more salty than the sea water was.
And it doesn't seem like diluting the brine with sea water before discharge would increase cost very much. From a 2010 presentation by Carlos Campos ("The Economics of Desalination for Various Uses") I get that seawater pumping and screening accounts for just 2-6% of the energy used in reverse osmosis.[0]
