It is a similar idea as that proposed by Turing. If you have submarines, and they move through the water and do exactly what you want them to do, then it is rather pointless to ask if what they’re doing is “really swimming”. And the arguments on both sides of the “swimming” dispute will make reference to fish.
If the submarine only “swims” when a human tells it to, I think this is the sense intended by saying a submarine doesn’t really swim any more than a scuba tank breathes under water. People “swim” with the aid of a submarine.
