When working in open drain, the pin will be pulled to GND whenever you write(false) and will be left floating whenever you write(true) (as opposed to normal mode, where write(true) will pull the pin to 3.3V).
I'd imagine that this technique might be sensitive to wire lengths and such, so you'd need to research / experiment it.
