In the FTP protocol, "passive" means that only one connection is 
established, originating in the client. All trafic goes over this 
connection. (In non-passive FTP, the server opens a second channel back to 
the client.)

No such differentiation exists in SFTP. There is only one connection.

The vendor may be using "passive" in a different sense, but I don't think 
it is a widely accepted usage.
