A cursory glance through the code seems to indicate that the specified line contains a reference to the wrong key.
"if ($PSBoundParameters.ContainsKey('ReplicationFrequencyInMinutes') -and"
should probably be
"if ($PSBoundParameters.ContainsKey('OptionChangeNotification') -and"
Every site link option contains the same check for the presence of the ReplicationFrequencyInMinutes key. I'm not sure if this is the intention, but it seems that if the replication frequency isn't also defined, the site link options remain the current values.
