Simple, It's double pole, it must be an isolator.
And I seem to remember when showers first started to become popular (pre 15th regs?) that the pull cord had to be within reach of the person in the shower.
not quite , the device has to able to be locked / secured in the off position to be classed as an isolator , and you cant do that with a pull-cord.
where as a switch for maintenance does not require this.
