It takes a long time to deliver these decisions. The majority opinion is written weeks beforehand, with hundreds of man hours put into it by the justices and their clerks. Alito would have already read and approved it (or he would have joined Thomas in dissent). They heard the arguments for the case on another day, this is just the deliverance of the ruling.
