Yes, it is correct.
Password is captured in clear by passsync service into the AD server 
witch is used by workstation for changing password operation.
Master AD server give password to slave servers in no-clear mode and 
crypted password can not be captured by passsync service.

No, you can't.

In the AD-FDS synchronization architecture, only one synchronization is 
allowed.
If you install two passsync services into two AD servers you take risks 
to create problems in replication.

cf : http://www.redhat.com/docs/manuals/dir-server/ag/8.0/Windows_Sync.html
"WARNING : There can only be a single sync agreement between the 
Directory Server environment and the Active Directory environment. 
Multiple sync agreements to the same Active Directory domain can create 
entry conflicts."

This is the point of failure of the FDS/windows sync architecture.
