pjang's answer of stayfoolish's 3rd question makes my confused

I am confused by the Pjiang's answer of stayfoolish's 3rd quetion. the questions:
how much is h1b transfer fee?
- http://blog.wenxuecity.com/blogview.php?date=200709&postID=27583#Fees

how long will it take?
- 2-3 mo generally

can I start working after file the transfer? Does the salary have to be same or more than current employment? and the job type has to be the same?
- Y, N, N


common sence shows the beneficiary can start to work once the USCIS receives the H1b transfer application paper.
