My suspicion is it has to do with controlling the number of queries being issued and from where or perhaps and more specifically, tracking the failover itself.
Once the failover occurred, the identity of the cucm-side ldap sync would change and AD servers might not handle that gracefully. I don't see why not but in a trusted-cert/LDAPS scenario it might have issues? Still seems like there could be a stateful token or something that could be passed around to whatever the active ldap sync node happens to be.
