You dont specify when the inspection was done. Was it just before takeoff or after the initial de-ice?...if it was just before take-off then it is a requirement if the minimum holdover time has been exceeded that a visual inspection is carried out prior to take-off.
As there is no hold over time for type 1 fluids then this may have come into play.
If it was still at the CDF I dont know.
