Yes, that is the main problem with what the Pope said. The women who use contraception in that case would be sexually active women, not celibate nuns. And the use of contraception to prevent pregnancy and subsequent birth defects is direct and therefore intrinsically evil.
It is like the case of a woman with a severe illness, whose life is endangered by the additional stress on her system of a pregnancy. The use of abortion is such a case is direct and therefore always immoral.
