Hey there John, see you in Florida again ??? as a retired power distribution design engineer that story MAKES ME SHIVVER Its NOT the safest or the correct or certainly NOT the NEC approved method.
Chief reason being instead of relying on Billy Bob or Bubba to be sure and remove or shut off that Genset backfeed breaker if its on and the genny is running given the right (wrong) set of circumstances it can kill someone. Similar the genset can be fried !!!!!!!!
Whats safe is a safety lock out slide type mechanism or a proper transfer switch so its impossible to backfeed the main.
SURE it can still "work" the way he does it but its not safe (potential for human mistake) and its not code proper
NEXT TO THE CONNECTED NEUTRALS, here's the deal:
A) If you only switch the Hots, NOT the Neutral, the Genset and Utility Neutrals can be bonded BUT the genset needs to have a FLOATING BEUTRAL
B) If you switch the Hots and the Neutral the Genset needs a Bonded Neutral, configured as a Separate Derived Source" plus connection to a Grounding Electrode
Where life and fire safety are concerned consult current practicing (that's NOT me too long retired) professional engineers and electricians and the NEC and don't risk your life on lay opinions !!!!!!!!!!!!!!!!
John T Too darn long retired EE so no warranty, consult professionals

Today's Featured Article - Product Review: Black Tire Paint - by Staff. I have been fortunate in that two of my tractors have had rear tires that were in great shape when I bought the tractor. My model "H" even had the old style fronts with plenty of tread. My "L" fronts were mismatched Sears Guardsman snow tires, which I promptly tossed. Well, although these tires were in good shape as far as tread was concerned, they looked real sad. All were flat, but new tubes fixed that. In addition to years and years of scuffing and fading, they had paint splattered on
