Unable to set PIN - Error: "PIN must not be the same as the user's phone number"

Question

We are in an ongoing Lync Server 2013 deployment and have elected to set default conference PIN numbers for anyone that doesn't have them currently set.  We decided to make the default PIN the same as the person's telephone extension.  I realize
this is not a secure PIN setting, but please bear with me.
When I use PowerShell to loop through the people that do not have a PIN set and attempt to set the PIN to their five-digit extension, PowerShell returns the following exception:
Set-CsClientPin : PIN must not be the same as the user's phone number (Error "18005").
At line:1 char:1
+ Set-CsClientPin -Identity GenericUser -Pin '13579'

sUserPinCmdlet
I know what you are thinking:  by default, Lync has the AllowCommonPatterns setting set to $false on the Global (default) PIN policy.  But I have created another PIN policy called "Low-restriction PIN Policy" that has this setting set
to $true and assigned this new policy to the users I am trying to set the PIN on.
According to
Microsoft's documentation on the Set-CsClientPin cmdlet, the description for AllowCommonPatterns is as follows:
"Indicates whether or not "common patterns" are allowed in PINs.
Common patterns include repeating digits (225577); 4 or more consecutive digits (991234); and
PINs that match a user's phone number or extension number.
If set to True common patterns (such as the PIN 123456, which includes consecutive digits)
are allowed; if set to False common patterns are not allowed. The default value is False."
Given this information, I do not understand why Lync Server 2013 is preventing me from setting a default PIN that matches their extension number when AllowCommonPatterns is set to $true on the PIN policy assigned to the user.
Any ideas on what might be wrong?

I just checked the management store replication status and it replicated.  I tried to set the PIN again and got the same error.  Here are my results:

C:\Users\user> Get-CsPinPolicy -Identity 'Low-Restriction PIN Policy' | Select-O
