Depends on what you mean by "clone". If you mean a bit-for-bit copy using dd or an equivalent, then you're correct. The file system UUID will be copied along with all the other bits of the old file system. If you mean "create a new file system on the new drive, then rsync the files over", then the file system UUID will not be the same. Unless of course you specifically go out of your way to copy the UUID as well.
