Careful here lest users ignore the warning in the wiki. Ancestor VM if called from dom0; Calling VM if spawned from domU. This is actually a weakness of current implementation.
A couple conservative wording changes:
The major benefit of this approach is that the Whonix-Workstation DisposableVM can be created in order to host a single application – usually the Tor Browser – without any risk that a compromise of the browser will effect any of your other VMs.
“without any risk” > “mitigating the risk”
Critically, a Tor Browser exploit will not effect (poison) later instances of the Tor Browser running in a subsequent DisposableVM session, because the DisposableVM is always started in a clean state.
“effect” > “affect”
“in a clean state” > “in its original state”
