Yes it does. AcidWeb is talking about *updating* metadata in existing joint mobi files, for which calibre will only update the first header record, i.e. the mobi 6 header record. He is creating his joint files using kindlegen, for the comic support, and then trying to use some tool to change the metadata records in the joint file.

I have no interest in adding support to calibre for updating both metadata records in a joint file, but patches are welcome. However, given that MOBI is a "fragile" format and making this kind of change would require extensive testing on various kindle devices/apps to ensure it doesn't break anything, dont expect to get those patches merged easily.

A better approach, IMO, is to simply add support for the KF8 fixed layout format to calibre's azw3 output plugin, when converting comic files (cbr/cbz).

That will require a bit of reverse engineering again, but it should not be too hard. However, I am currently too busy writing Sigil's replacement to get involved.
