On the page that OP linked to, there's statements such as:
"The Everything Tor OS - All traffic is routed through the Tor anonymity network. No exceptions. Whonix is the "All Tor Operating System"."
"Cloaking your typing style - Your typing behavior can be used to identify you. Whonix prevents this with a cloak for your keystrokes."
"Live Mode - Whonix offers a much requested Live Mode. After the session all data will be gone."
So I don't get your point. Of course if you want to know how, in detail, you have to read the documentation.
