An H-1B question, please help

I have an H-1B visa question for my hu*****and and hope someone can help me. My hu*****and has H-1B visa valid from Oct. 1, 2007 to September 29, 2010, petitioned by his company lawyer. In the lawyer letter, he wrote “Please note that this H-1B visa petition is only valid for your employment with ***(the company name), and is not transferable to another employer.”. Do you know what “is not transferable to another employer” means? Does that mean my hu*****and has to use CAP again if he wants to change job to another company? Can he work after receiving the receipt filed by the new company and not use CAP again? Many thanks.
