Thank you for your question. Please permit me to assist you with your concerns.
A POA is not the same as conservatorship. A "Power of Attorney" is akin to someone being hired to be another's general manager, but that other person remains in control, with the general manager remaining subservient to him. In that sense so long as your father has a 'moment of lucidity' and can legally consent and make his wishes know, a POA holder cannot overturn him. So long as your father within his faculties and knows what he is consenting to, this can still be lawfully performed.
