No, it also covers the data. As long as you don't delete the rollback subvolume, all the original data should still be there, uncorrupted.
Even if you disable copy-on-write, as long as the rollback subvolume is there to lay claim to the old data, it's considered immutable and any modification will still have to copy it.
