You CAN exit through Southwark Station from Waterloo East without being charged extra. I've travelled from Charing Cross to Waterloo East and left the station via Southwark twice in the past 10 days.
When you pass through the barriers a complicated series of deductions and additions is made to your Oyster PAYG balance, but it is adjusted to the correct National Rail fare by the time you pass through the final set of barriers.
The only people who need to pay for platform tickets are those who arrive at Waterloo East using paper tickets (ie from outside the Oyster PAYG zones).
