It's not. If the SID didn't change the count won't increase. Not sure what happened, but KMS is seeing a request from a SID it has not seen before.
If you can't get sysprep to work on a pool then about all you can do is keep running sysprep.exe with OOBE and the generalize option from C:\windows\system32\sysprep a bunch of times on one machine until you get activated. But I really think you should track down why the sysprep option isn't working in View. In this business, mysteries are never good.
