It is different. --bind does only 1:1 copy (files are written to the source directory, for example), unionfs puts the changed files in one of the underlying directories. > Hmm.

Is that better: The unionfs driver provides a unification file system for the Linux kernel. It allows to virtually merge the contents of several directories and/or stack them, so that apparent file changes in the unionfs end in file changes in only one of the source directories (which makes possible to "change" files on read-only filesystems).
