I figure that you'd be very unlucky to to get the ink actually spurt into your mouth! I think it's probably to do with changing the pressure in the barrel rather than really sucking the ink through, IYSWIM. The type of pen with the roller ball is the only one I'd do this with - anything with any kind of chemical smell that stops working gets ditched (or refilled if it's refillable).
