Voting to end the debate in the Senate means that it goes to the House. If the House then votes for it, the bill only needs a 51-49 vote to pass in the Senate. That, in essence, means that Brown voted for the bill.
As for my source of Brown voting yeah to Obama's latest federal judge nominee, I heard it today on the Howie Carr show. A caller stated that Brown voted for Obama's nominee and Carr agreed with him. Unless I heard wrong, or there was a misunderstanding, that was what I heard on the radio.
Could be worse...
