This author almost completely misses the point. The basic architecture behind SHA-2 is similar to MD5 and SHA-1, and the fact that attacks are possible on MD5 and SHA-1 means an attack could be possible on SHA-2. Then if SHA-3 used the same architecture again, a weakness in SHA-2 might lead to a weakness SHA-3. Then both SHA-2 and SHA-3 are insecure.
Since SHA-3 is now based on a totally different architecture, any weakness in SHA-2 has no effect for SHA-3. At the same time, if someone does find an attack against SHA-3, SHA-2 is still secure.
