Yea, because they consider threatening death coercive. But funnily enough, a 50+ years in prison threat when the state knows you will die in prison due to age/health, not considered coercive and doesn't qualify. It's the threat of physically being put to death that puts it over the line for this sort of plea for the courts to recognize the threat being made as 'coercive'. So The Justice System absolutely understands that pleas come with implicit threats. Or you can explain that as 'this can sometimes happen'.
