It was my understanding that the reason you have up to 72 hours to use the MAP was because it took at least that long to fertilize anyway. After 72 hours, if it works, consider yourself lucky.

That's what I've always understood -- EC can stop a fertilized egg from implanting. From Planned Parenthood:
According to the Food and Drug Administration (FDA), "Emergency contraceptive pills...act by delaying or inhibiting ovulation, and/or altering tubal transport of sperm and/or ova (thereby inhibiting fertilization), and/or altering the endometrium (thereby inhibiting implantation)" (FDA, 1997).
I thought something that inhibits implantation would not be looked favorably on by somebody who is opposed to abortion.
