Sounds like it. This is not a vaccination. It may be possible that while these antibodies are working the body might also “learn” the virus, thus providing immunity, but that would be a side effect of the infection.

For other coronaviruses that infect humans there the adaptive immune response isn't particularly strong and doesn't last. E.g. immunity to HCoV-OC43 lasts no more than about 12 months.

This is a reason to suspect that a vaccine may not be easily developed; so antibody therapy (and/or anti-virals) might be the best we can do.

If the antibody therapy was highly effective and could be produced at scale for a tolerable cost, it would probably be a pretty effective tool. Though monoclonal antibodies aren't known for being particularly affordable.
