There'd still be at least 2 buses on Newcastle boards which would be single deckers, even if those 2 were allocated.
Obviously it's more than possible that 7523/39 had defects which meant they couldn't have been allocated to the X12, or engineering (who I'd imagine trump a "note from an inspector") needed them later in the day.
