Yes. That's how it works. The result is a new ISO freshly produced by
jigdo-lite and its main worker jigdo-file.
The old ISO is supposed to still exist afterwards.
We only disagree about this statement of yours:

The old ISOs must be readable (i.e. mountable) and the directory where
jigdo-lite creates the new ISO must be writable.
We agree that a local set of DVD ISOs can heavily speed up the creation of
slightly youngers ISOs. (With very much younger ISOs you may have not
much success with looking for their packages in the old ISOs.)
Have a nice day :)
