Question remains, would it be recorded the moment the spars moved from their open position or would a record be made only if the spars reached their closed position? In other words, if an uncommanded partial closing of the spars had occurred which rectified itself before they reached the fully closed position, would that have been recorded? If only recorded when reaching closed position: spars take up to 15 seconds to fully close so if an anomaly lasted anything less than 15 seconds and the spars moved back to their open position, they could have restricted fuel flow considerably without having a record of it and, as reported, the spars would be found in the open postion.
The report uses the term "movement," which would seem to cover that:

A detailed examination of the spar valves and their control system revealed no pre‑existing defects and a thorough review of the control system indicated that uncommanded and unrecorded movement of the spar valves was not possible.
