Wait... no... that example is only valid for the "attacker takes over existing mining pools" case, where formerly honest miners are co-opted to be evil (or gang up in a cartel to be evil). @p{par}

If somebody collects as much hashing power as the rest of the network combined and @p{(it}then@p{it)} suddenly attacks, then yes, indeed, difficulty stays the same, the attacker gets all the mining rewards, and there are twice as many stale blocks as before.  Attacker gets 6 block rewards per hour. @p{par}

If they were to mine honestly, blocks would be created twice as fast until difficulty adjusted, so they'd get 6 block rewards per hour for a week (same as if they decide to attack). Then difficulty would double, and they'd get only 3 per hour.
