So the strategy is to leave no seat assigned so that at check in I can potentially be allowed to choose any open coach seat?
No his point was wait until T-24 when elite passengers switch their regular economy seats to the ones you mentioned. Then their regular economy window seats will be open for you to take.
Choosing or not choosing a seat when booking doesn't change anything for you - you should be on the lookout for seats, or use ExpertFlyer, as they open up online.
