"Pro-choice" but glad about no choice?

Director Penny Marshall talks about her abortion in her new book and says something which undermines her pro-choice position:

She is also vocal about her support for abortion rights after her own experience with unplanned pregnancies. Her first pregnancy with her boyfriend-turned-husband resulted in her daughter, Tracy. Her second, following her second marriage and divorce to Hollywood director Rob Reiner, resulted in an abortion. "I'm pro-choice. But I'm glad that there was no choice back then, because I have a wonderful daughter and three grandchildren," she said.
