There is still significant sharing that can be achieved inside a VM, plus, a lot of the sharing come from zero pages (full of 0) which is still performed accross VMs.
Another benefit of the salting mechanism is that it allows the administrator to define groups of VMs that are trusted in which sharing will be performed.
disclaimer: I work at VMware and wrote the salting code.
