Also a possible senario:
You are tight on disk space or you have large files in /home (but not in ~/Live-usb-storage), that you don’t need built into the remaster file.
I had a situation like this, where I was using home persistence, but I was starting to run short on disk space. Since I had the home persistence file, omitting the /home hierachy from the remaster made a smaller linuxfs file (remaster file), and eveything in /home was still there, so long as I used home persistence.
