Greg, what changed "a few years ago" was that a switch ould only say "off" IF it truly cut off the power. Illuminated switches - an example of a switch that doesn't completely cut off the power - can't SAY "OFF" if they power the lamp by letting a minor amount of current through.

(By way of contrast, if an illuminated switch did disconnect the power, using a neutral or ground path to allow the bulb to light, then they could say "OFF").
