It depends: the traditional "plug cock" used for low pressure water service and gas-lighting had no directionality: if it was 'on' you could turn it either way through 90 degrees to get an 'off' condition. And a 90-degree turn either way would then turn it on.
The lever/handle at 90-degrees to the pipe [achieved by turning either way] was the traditional sign-of-offness.
Hard detents on such valves are a rather recent idea!
