Why not? (not arguing, just want to understand)

If nothing else, it confirms that earth is earth.

Example: troubleshooting a hypothetical faulty appliance, at the
appliance I measure 240v between L and N, and 0v between L and E.
Either the flex is 2-core or there is an earth problem somewhere.

I'm intrigued too, especially as N and E are joined together at the
supply pole outside....
