No, that's not how the appeals process works in the US.

The Supreme Court speaks to the specific case before it, lower courts then apply the precedent as best they can to other cases, and SCOTUS occasionally tells them they've done it correctly or not in future cases.

You see this in gun rights cases pretty frequently, with lower courts sometimes getting it wrong and SCOTUS correcting them.

As for Roberts, he made this explicit in his footnote:
"This opinion also does not address the issue, in light of the potentially distinct interests that military academies may present."
