If so, you're right that it's not binding. Higher courts can, and do, defer to lower courts — where the higher court concurs with the lower court's legal reasoning. But that requires the case to have appeared before an appellate court.
The reason for this is simple: trial courts consider questions of fact, while appellate courts consider questions of law.
Similarly, so-called "horizontal precedent" applies between peer appellate courts — and, again, isn't binding.
To my understanding, the only way this becomes more than informally precedential is if it's legitimately a "case of first impression" — and that would apply IFF this case is legitimately the first place this question of law was asked, and only until it's heard and ruled upon (or not taken up) by an appellate court.
