Nick Robinson in fine spinning form

The BBC's reshuffle news contains this odd sentence:

"BBC Political Editor Nick Robinson said he understood that Mr Darling had turned down a move to the Home Office and Mr Purnell had been "sounded out" about the job of education secretary, which would have paved the way for Mr Brown's ally Ed Balls to become chancellor, but that was not now going to happen."

What odd wording, was it Alistair Darling's turning down of the Home Office or James Purnell's turning down of Education that blocked Ed Balls' move to The Treasury? The wording makes it sound as though it was the latter when surely it was Alistair Darling's refusal to move that stopped Ed Balls' promotion. Finding a replacement for Ed Balls would have been relatively easy.
