The units are meters, but meters on the projected map not great circle meters on the surface of the earth. What osm2pgsql does when you import in that mode is to project the data onto a giant flat sheet - effectively it unrolls the globe and stretches it until it is flat. The resulting coordinates are in meters but meters on that imaginary projected surface.
