Alabama execution without requested imam

Story here.  It's not as obvious to me as it seems to be to some in the Twitter-verse that the Court's 5-4 split on the stay shows hypocrisy regarding religious freedom (because there are questions about procedure, timing, etc., and a general policy regulating who can be present in the execution chamber is reasonable) but, given what I know at the moment, it seems to me that the Court should have left the stay in place (and that Alabama and other death-penalty states should anticipate the need for chaplains of multiple faiths).
