Basically, because the SCOTUS said so:

"Our decision in these cases is concerned solely with the contraceptive mandate. Our decision should not be understood to hold that an insurance-coverage mandate must necessarily fall if it conflicts with an employer's religious beliefs."

Of course, there's nothing to stop suits from being brought regarding other kinds of religious beliefs. And I'm sure they will be!
