The authors' say that "The data also argue against an image decomposition mechanism" as an explanation of the snake illusion. This claim hinges on having controlled for apparent transparency/illumination effects in some of their stimuli. However, as they themselves acknowledge in the article, their stimuli still present such effects, despite the investigators' having removed some features, like X-junctions, commonly associated with transparency effects. Thus, their claim vis a vis image decomposition cannot be said to have been corroborated.
