I think this is describing a kind of 'synergistic' use of muscle groups. They work together to produce a better result, but the lat isn't actually raising the shoulder, instead it's providing stable support for the back making it easier for the Deltoids to do their job.
I was just playing a bit and yes the deltoids are involved to some degree but not the other key shoulder muscles most folks engage and the shoulder unit can remain relaxed and low, supported by the core.
