As @theDucks said, the "match to library" is only used if calibre cannot match the book on the device to the library. Or got it wrong.

Updating the metadata on the device after sending the book depends on the device. Some devices read the metadata from the book each time it is needed, so just resending the book will do it. Others build a database of some sort with it. For these, the database or files that contain the metadata needs to be accessible when the device is connected. Some are, some aren't. And someone needs to write code to update the metadata on the device. I don't know anything about the Pocketbook Touch Lux 4 that you list as your device, so I don't know how it manages the metadata. But, for most of the devices, the calibre support for them means you need to resend the book to update the metadata.
