No, you are just victim of a kernel bug in the iso9660 filesystem.
Hardlinks are not correctly copied as hardlinks, so they are split into
individual files and therefore require more space on the destination
filesystem. If you replace all files that are >= 1 Byte and identical by
content to each other, with hardlinks, the allocated space should shrink
