This is a confusing way to put it...but once I deciphered what was meant by it, it helped me a lot. I was having the EXACT same issue. Basically... there are only two possibly ways for the wires to go...it's a bit like a puzzle. One way is right and one way is wrong.
The black wire from one black and white wire pair (in the same protective plastic coating) coming from the ceiling is wired to the other ceiling pair's white. The white that is now by itself in the ceiling (no other free white wire there) goes to the ceiling fan's white wire. The last black wire that is now by itself in the ceiling goes to the ceiling fan's black and blue wires. Grounds are always together and screwed to the box in the ceiling. In my case the two grounds from the ceiling were actually still one wire and screwed into the ceiling box already so I wired the green wire from the fan seperately to the box as well.
If you start by connecting one black ceiling wire (from one black/white pair) to the opposite (black/white pair) white wire, then connect the leftover white wire from the ceiling to the white wire from the fan and the rest of the wires together (excluding the ground wires); so... leftover black ceiling wire to black and blue fan wires it will either work...or it wont. If it doesn't work, you should then disconnect everything (or disconnect wires as you go to make the process less confusing on yourself) and connect the first black ceiling wire to the other white ceiling wire (the one it is has not yet been connected to) and repeat the process above.
Black Ceiling Wire (HOT) => Opposite White Ceiling Wire
Other White Ceiling Wire => White Fan Wire
Other Black Ceiling Wire => Black and Blue Fan Wire
This is NOT a safe way to do it (the whole trial and error thing), however it will work if you have a safe breaker system set up. I got lucky and it was correct on my first try.
I hope this way of wording it will help someone work their way through the process. If not...hire an electrician like we all should be doing!
