Thanks for the answer! It was clarified in the website, but the "9x" sentence was still ambiguous. Very often, image processing people will understand "resolution" as a linear unit, like dpi or gsd. Using its square seems strange, likely only useful for marketing purposes, and thus a red flag for technically minded people.
That said, 10cm per pixel is impressive if you manage to pull it through! Cannot wait to buy these images!
