I can see where he's coming from. Any differences in the data caused by encryption or compression of the final video files don't even come into play here unless the raw video data they are produced from is bit-for-bit identical from one episode to the next, say in a precise lossless format like CCIR 601. Maybe this is true at the production company but I wouldn't be surprised if it isn't. It would actually be somewhat interesting to know what the typical workflow at the production company is for gluing the title sequence together with the rest of the show. Your blog post doesn't do enough to clarify these issues.
