That way you have full agency over when you switch out. And given golisopod gets a powerful +2 priority stab and a lesser +1 priority stab it's pretty abusable too.
Since it has a massive attack stat it doesn't really need to rely on any boosts that would be lost if it switched out either. It would be a great momentum machine that could even tank a hit and then switch out if necessary.
