I believe this is in reference to those who have breakthrough infections while already vaccinated, hence acting as a "booster".

Unvaccinated with an omicron infection is not necessarily the same thing, and isn't likely to have as strong an immune response.

“During May–November 2021, case and hospitalization rates were highest among persons who were unvaccinated without a previous diagnosis. Before Delta became the predominant variant in June, case rates were higher among persons who survived a previous infection than persons who were vaccinated alone. By early October, persons who survived a previous infection had lower case rates than persons who were vaccinated alone.” https://www.cdc.gov/mmwr/volumes/71/wr/mm7104e1.htm

I’m not sure what you think you are saying. But vaccinated + previous infection is superior to either alone. Hence the “super” booster nomenclature.
