There is only one original bitcoin and those who copies bitcoin to create another cryptocurrencies will always be called altcoins or alternative coins. It will remain as the leading cryptocurrency in the market and neither hardforks nor segwits will change that. For the few years, many developers attempted to create alternative virtual coins to challenge the dominance of bitcoin but til now no one is able to overtake its current top position.
I will claim that even if one of the forks was able to overcome bitcoin and got a bigger market cap than bitcoin, that will not make it the original, that will only make it the most popular coin or the coin with the most money backing it, there is only one bitcoin and that is the one created by satoshi and maintained by the core devs and it does not matter the amount of forks there are that is never going to change.
