Is it correct saying that on the 1st August BTC was upgraded to segwit1x
and the split off chain known as Bitcoin cash was given a 2mb increase
to its block size (but didn't get the segwit1x upgrade)?
 
Also for the coming November fork is it correct that BTC which now has segwit1x
will not change and the split off coin B2x (or whatever it will be called)
will be given the segwit2x upgrade? So B2x would now have the extra space
on the block given by segwit1x and also increase to a 2mb block size given
by segwit2x.
