Questions about the service policies or practices of a registrar are best addressed to the registrar. It's their policies and practices that you are questioning and who better to explain why or how they are applied?
In you case there appears to have been an exception to a rule. Maybe they made a mistake? Maybe some other small fact controlled the exception.
Please direct your question to the registrar and let us know what the explanation is. Should you follow up please be mindful that the WebmasterWorld TOS prohibits direct email quotes.
