No it don't....well it does but only once the valve is open. When it is closed there is no pressure between the slug and the spindle.
I have on many occasion removed the spindle and nut to clean the o ring or spindle shaft. Nothing bad has ever happened. In fact you know there is no pressure there becuase once you have moved the nut a quarter turn you can undo it by hand.
