Yeah, doesn't make sense to me either.
On the right, you have Roberts, Scalia, Thomas and Alito.
On the left, you have Ginsburg, Breyer, Sotomayor, and Kagan.
And then there's Kennedy who, I think, would vote with Roberts et al. on this issue.
Hell, you might even get one of the justices on the left to vote with Roberts and company.
