Well, some comment here. Yes, by today's code it is an error.
But it's not like the typical (at least for me) error where
I put the &$*%+*! resistor in the wrong place on the schematic
or leave the damn thing off altogether, etc. It's a NEC code
error because they changed the rules after the game was started.
Electrician friends tell me it used to be allowed by code years
ago. They call it "Chicago wiring" and say they still run into
it on occasion today. I don't know when the rules changed.
