Not quite: every amount of salary you claimed tax back on in the UK has to be decleared to the french tax man. French taxes are lower than the uk refund tough. I did some contract work for a UK company and the french taxman recently found out... The inspector, who I dealt with, told me I was not the only one he was after and a friend in EZY-Paris told me the french tax man is after them as well. So be carefull and seek advise of a professional!
