It could be possible as CfB is from Belarus and maybe the two were conversing in Russian, which may explain why CfB never made the discussion logs public?
Not saying it is a bad thing. If he was really BCnext then he would be a good public face, but obviously most crypto developers try to remain anonymous to avoid the securities law. But the understanding here is that a lot of websites reporting him as being the founder of NxT is a misprint (he's the creator of SAE which is a different thing).
