Yes; obviously a broken neutral is a problem in itself, but that's usually a relatively minor issue that just leaves an outlet inoperable at worst.

The way this plug is wired is such a hazard that if it was plugged into an outlet with a broken neutral, it could be potentially deadly for an extended period of time (as opposed to tripping a breaker, only presenting a hazard briefly).

A really simple example: an outlet that has worn out, meaning the neutral does not always connect with the inserted plug. You insert this plug into that outlet and the casing of the appliance you've just plugged in is now live.
