I said that you can't verify the header until you have downloaded the entire block - meaning the time between a false header being submitted and the last transaction in the block being downloaded is time the miner either abandons its work on the last real block and then sits idle or risks hashing a new block prior to verifying the false header. He implied that you can somehow verify using the PoW. I demonstrate that you cannot. I'm not sure how you could have missed it.

No, he said that blocks are verified to have enough proof of work put into them. You were confused.
