I also tried it with those updated earlier this month, and all were said to have been updated.
Is it because the automatic update modifies different elements from the manual update?
Thanks for the plugin again, anacreon
The driver will update less metadata than you can in with the plugin. But, the rules are roughly the same. The main difference is some customization and the plugin does other things.

Firstly, the metadata that the driver can update is: title, author, comments/synopsis, series info, subtitle, publisher, published date, ISBN and language.

Then, the driver is only changing common displayed metadata. The plugin is needed for things like the reading direction and the date added. And the driver will always use the plugboard. That matches what happens when a book is sent to the device. Calibre will update the metadata in the book using the plugboard.

There is no template for the comments/synopsis because calibre now supports comments in the metadata plugboard. The subtitle does have a template a there is no other way to do this. Of course, it could be just a column, or a more complex template to have something like the page and word count displayed.

Overall, if you were updating the metadata with the plugboard frequently, you shouldn't expect to many changes when you first turn it on. And after that, there should be even fewer, unless you make a big change somewhere.

One difference I did forget about is that the metadata plugboards can be format specific. So, you can have different plugboards for epubs, kepubs, PDFs and anything else you have on the device. But, because of the way the KoboTouchExtended driver works, if there is no kepub specific plugboard, the epub plugboard will be used.
