That likely(*) means they are keeping Natural ones as automatic failures for skill checks and simply removing the incongruity of a 1 failing a difficulty 0 check.
I was wondering about that too. I didn't see anything that positively confirmed that 1s and 20s in skill checks were still handled that way as, while I certainly failed skill checks, for once I didn't roll any 1s. But my assumption is that 1 and 20 have been kept as auto fail/success. Which I know isn't RAW and many folk don't like, but actually I kind of do.
In fact, I think during the PFH when trying some of those harder dialogue checks in the hospital it might even have been mentioned that a natural 20 would have been a success, and if that's the case I'd assume that would be balanced by a natural 1 being a fail.
