The original spec didn't really address fairness per se; Van's 88 paper 
is the earliest that made that assumption (somewhere around page 10). 
The implication is that per-connection is defined as fair.

It would have been more precise to say "most studies of TCP fairness 
assume per-connection is the definition of fair".
