is it bottle carbonated? I would be surprised if it was. but like said above that yeast is stressed out super hard.
I would assume that for the initial fermentation they would use a clean ale yeast then pitch the hard hitting high alcohol yeast when things get more intense.
If you want to brew it, if you have beersmith you can add-on the CYBI clone recipie from the Brewing network. They pitched it initially with a 2L starter of WLP001 (Cali Ale) and followed that at high krausen with another 2 L starter of WLP099(high gravity) at the same time they add the sugar.
