I'm lost!
The original/existing connection, in the original location of the sink, is down into the concrete slab. As I understand it.
"the tee that is sticking out of the wall"?
He he was planning to go down under the dishwasher, I would assume he would be below the slab. If he was actually going that far(which maybe he wasn't doing??), just connect with drain line already below the slab and not rise back up. ???

yes. that is what it sounds like.
