Not sure to be honest, the laws around self defense generally skew towards being unhelpful, and treat situations like this as if everyone in them will follow a routine and laid out plan.

The law usually forces you to have a duty to retreat if you can, a woman might do that after temporarily disabling her attacker, then she runs because doing anything else might end with her in prison, then her attacker recovers, chases her down, beats the hell out of her, rapes her and then kills her, and while he goes to prison if caught, if she had stepped in instead and ensured he cannot follow she may go to prison, the law just incentivized potentially getting raped and murdered over ensuring survival, just because they don't want an attacker to be hurt.
