While this may be true for Nexus devices, it doesn't apply to the Moto X.
The Moto X bootloader has 3 states:
Locked, Unlocked, and Re-Locked
Once you have unlocked, if you subsequently re-lock, the status changes to "Re-Locked". You can NEVER get it back to "Locked". So regardless of whether you get your code from the official Moto Unlock site or the Middleman, they still know that you had unlocked previously. There is no way around this...
