I highly doubt that he will be able to do so either. However, that does not reflect on whether or not he is the one that is behind the attack on Comodo, which has no real indications of being difficult. Comodo claims that it must have been an organized, planned out attack because they knew which domains to get certificates for. That does not explain why 3 were generated for one domain and one for 'global trustee'. Nor does it take a genius to figure out a set of domains you would want certificates for depending on what you are planning to do (in this case, it seems like attacking large webmail providers).
