Name check expired ?

[IluvmyLi]

Ok so in the GUZ speaks forum, GUZ says that the name check done at the NVC level expires after 12 months. So if for some reason we are having to go through a 2nd name check once the case arrives at GUZ, then the 1st name check done at NVC could very well expire while waiting on the 2nd name check. Then if the 2nd name check is ever completed does the 1st name check have to be done all over again because it expired? Could the 2nd name check expire while the 1st is done again? Is the dog chasing it's tail or am I confused again?
