No. As I understand Dembski - at least when he was saying this kind of thing - he admitted that the environment could be complex and hence that NS could instill complexity in evolved organisms. "But", he then suggested, "where did the complexity of the environment come from, if not from a Designer who crafted an environment capable of directing the evolution of man (in His own image, etc.)"

Dembski, these days, admits to being a YEC, but the reason he is a YEC is based on a kind of appeal to Occam. "If we believe in God anyways, for reasons of Theistic Evolution", he seems to argue, "Why not take God at His word and believe in 6 days and the whole schtick?"
