Yeah. 'Suicide plug' Is a misnomer. Should be 'homicide plug.'

The danger isn't plugging both ends into the same circuit. The danger is when there's a downed power line, somebody plugs a generator into their outlet to power their own house. The genny backfills the line, so this line that everybody thinks is dead is suddenly live. All of a sudden the poor lineman who is trying to fix it a mile downline gets electrocuted while standing on top of a 30' ladder.
