rollback a filesystem and then realize, I wanted a file from the original file

I read the section on clones here:
http://docs.sun.com/app/docs/doc/819-5461/gavvx?a=view
but I'm still not sure what clones are.
In simple terms, writeable snapshots.
They sound the same as snapshots. From what I read, it seems like it is
possible to snapshot a filesystem, clone the snapshot and then rollback the
file system.
You have to promote the clone before you can destroy its source snapshot.
At this point the clone will be the same size as the data changed during the
rollback? So from the clone, files that were unique to the filesystem before
rollback can be restored?
The clone will be a clone of the filesystem at the time its source
snapshot was created.
