There may be something more general in your theory but in the precise terms stated it doesn't hold. For instance, Procellariiformes can fly with the feet exposed and trailing or with the feet hidden, tucked forwards into the belly feathers. Both strategies are shown in the photo of two Black-winged Petrels in Seabirds in the National Photographic Index (p. 226). See also p. 165. The feet are not concealed in the undertail coverts because in some species they extend beyond the tail when 'trailed'.
