Yes, but subsequent checks to ensure it is in the correct position are done only
after the initial relevant maintenance procedure has been carried out when first discovered. If a light comes on during taxi, then the maintenance procedure cannot have been carried out as the bulbs would have been removed. At that stage, you have no idea whether or not there is a bigger hidden problem and that the flap is indeed u/s. It is not acceptable for the light to come on and just go anyway because it looks right from the cabin, without first having had it checked by the engineers to ensure that the leading edge device does indeed work correctly. You are then operating under an ADD for which a visual check is required before each take off and landing.
Picking and choosing individual bits from the DDPG to suit doesn't work. It can only be taken in context of the
whole procedure.
P.S. It's metabolix, not metalibox. It helps if you read things properly

Saves a lot of confusion when reading DDPGs and QRHs
