No, he's right... at least mostly. Unless the RWP was drained fully (this will not happen over time- only if it was drained or blown out), a "dry start" isnt actually dry- there is some residual water left in it. A quick start without water is NOT going to shred an impeller. Im talking 1-2 seconds... not 30+. I dont trailer regularly, so Im not subjecting the impeller to this practice on a regular basis... but on all the boats I own or work on, I do a quick dry start before heading to the ramp... sure beats monkeying around once you get there. I get 5+ years out of my impellers.
