I don’t know where this author gets his facts, but everything I look at says the Fed’s balance sheet has gone from around $775 Billion in 2007 to $2.9 Trillion at the end of 2012...no sign of “staying the same” or “going down”.

Look here....
Today, the Fed’s balance sheet is $1.3 billion smaller than it was at this time last year. Last week it was $19 billion smaller. The largest year over year growth the Fed balance sheet has shown since QE 3 was announced occurred on November 23, 2012 when the Fed balance sheet was a mere $48 billion larger than it was at the same point in 2011.
He's talking about end of 2011 compared to end of 2012.
