cisco asa ftp mode passive command

As per cisco command reference,

"The ftp mode passive command sets the FTP mode to passive, which is the default. The ASA can use FTP to upload or download image files or configuration files to or from an FTP server. The ftp mode passive command controls how the FTP client on the ASA interacts with the FTP server."

So this command is for traffic that originates from or destined towards the ASA right? Playing around with this ideally should not affect any ftp traffic that passes THROUGH the ASA ?
