You have a point.
Mars does not have exactly the same average as the Moon and I should have said about the same. Compare the average temperature of Mars the Moon and other planets and you will see that a < 40 C difference is comparatively small. This does not change the fact that Mars would be even more cooler compared to the Moon than it is if it weren't for it's greenhouse atmosphere.
Earth gets the same average insolation as the Moon, but reflects more because it has a higher albedo. Mars is closer to the Moon in albedo, but also reflects more.
