I smell what you're stepping in. The arcing issue i beg to differ, for the factories I've worked in where half an inch or more is exposed, on terminations that i have been around for 40+ years, I'm given to believe what's here is minimal risk. The bolts wouldn't allow me to land any deeper tho I do have the same note often so fair.

That said, i recently heard of two linemen who basically got vaporized while doing everything by the book. No cause was ever found. Modern electrical theory is indeed still theory.
