It's a far cry from a nitpick, because disparity between inertia and gravitational pull makes all the difference when trying to slow down or come to stop.
Suppose a moon explorer needs to slow down rapidy, for example upon encountering an obstacle.
On Earth, the 150 pounds of suit's inertia is countered by 150 pounds worth of gravity, which provides for some good traction, through friction.
On the Moon, however, the 150 pounds of suit's inertia is countered only by (apparent) 25 pounds of gravitational pull, which gives much lower friction.
Suddenly the haples moon explorer finds it much harder to come to hald -- the distinction between inertia and gravitational pull, while apparently a nitpick -- has real effects.
Every Earthian has an intuitive expectation of gravitational pull, and thus possible friction, in relation to mass, and so we tend to skip the distinction in casual conversation. On the Moon, this relation is much different and should be taken into account.
