Thanks that's very helpful. 
I've read there's a vote and if it's below a certain percentage the split happens. What if it were above the required percentage? Does this mean there's no split and segwit2x is activated on BTC?

Not sure if you found your answer or not, but Bitcoin Segwit did not split into 1x and 2x. At least there were not enough 2x miners to keep it alive with any significant value. We are left with just two primary forks, though a Bitcoin Gold also came on to the scene, splitting off from Bitcoin Segwit.
