Co2 iirc is a physical extraction, like bubble hash, while this is concerning solvent hash, a different product.

The correct way to extract solvents is under vacuum.

Supercritical CO2 is a (very non-polar) solvent. I can't imagine what would make that a physical or mechanical extraction.

Good CO2 extraction uses two passes at different pressures. One to extract the terpenes and one for the cannibinoids.
