Somewhere yes, @michail1 was right too, there is indeed a God mode, and the magic was (among others) to change the verification steps
They used it between the 11th and 14th of december to apparently transfer all the coins to themselves, except maybe some but this just means that you can't claim anything without them, because there is nothing left
All of this is in the code and even commented (if (godmode) bla bla)
Currently writing a gist about what they did and how, I think I am close now, again it would help if I could get the hex output of one of their transactions (if people here can inquire/relay somewhere else maybe...)
Please see

To summarize the UB team used a God mode during 3 days after the fork to transfer everything (except maybe phase 1 addresses fulfilling their requirements that nobody understood) to their miner using the key of their generator, and now they should refund the addresses that did fulfill their phase 2 requirements
