I got an impression from the article that disassembly was what he did to explain the binary differences that remained AFTER he corrected for timestamps/certificates/etc.
Your impression was wrong. He showed all of the differences in the screenshots. That's how few there were. Not a single bit of the code portions was different. Only a handful of metadata bytes, plus appended certificate.
The disassembly was only there to be cute and emphasize the point.
