Not sure why you think so. It's the same guy, he was been at the forefront of trying to discredit the any notion of a "lab leak" all while being involved in research in Wuhan involving genetic manipulation the infectiousness of corona viruses. That doesn't necessarily mean that he is trying too hide an actual lab leak, or that there was one at all, only that he behaved unethically when he didn't disclose conflicting interests. The why is interesting, but can only be speculation: could be political seeing that everything is so polarized nowadays: when the "lab leak" was first vented it was seen as a republican (Trumpian) notion that could lead to intensified clashes with China. But reading the correspondence brought to light by the Intercept and RightToKnow it seems that major fear from scientists was that lawmakers might shut down GoF research if a "lab leak" was found credible - something most of the big names in virology are heavily invested in, viewed as a necessary tool in future pandemic control.
