You mis-characterize the ruling.
The court did not rule on the merits of the case:
"The Court expresses no view on the merits of the cases. In particular, the Court does not decide whether petitioners’ religious exercise has been substantially burdened, whether the Government has a compelling interest, or whether the current regulations are the least restrictive means of serving that interest."
In briefs requested and received after oral arguments, there was an agreed to different approach where the Little Sisters didn't have to submit a form (their objection) and the their insurer would still cover contraceptives. Given that change in circumstances the cases were remained back to the appeals court level for re-hearing.

A per curiam order does not set precedence.
