One is the fork and the other is the original. By not taking the Bitcoin name the Bitcoin Cash group has already admitted that they are the fork. They should be proud about it and give themselves a new name that stands for their ideals.

That said I personally don't believe that the name will make a difference in this battle.

In terms of how chain splits work there is not a technical differentiation between a "fork" and the "original". In the case of the hard fork on block 478559 there was a pretty significant change to the consensus rules (EDA, 8MB blocks & no segwit).

What happened on block 494782 was also a fork in some respects, there was well telegraphed plans to change the consensus rules on that block, but no one mined/accepted blocks with those rules.
