That's harder in practice than you make it sound. Firmware updates for Intel ME are handled through OEMs, it's not a file that Intel publishes that an interested person can go to their website and download. The article claims that such a patch has been released to OEMs but is being kept under wraps, which might make it hard to determine when it actually ships in a downstream update. Even if you have a file that you know contains the binary blob of updated firmware, reverse-engineering it to determine what it does differently compared to the previous version is very much non-trivial.

I suppose it would be possible to download the update individually and examine its contents, but, as you point out, it would be extremely difficult to work out what it was doing.
