Probably to make things more simple. Generally, buggies all use the same diff ratio, so why bother to figure that in all the time? But, some do use different ratios which would throw things out of whack. So, to cover all the possibilities, the overall ratio is broken down to diff and spur/pinion.

When someone says "you are geared too high", they probably are familiar with the rest of the setup and know the general ballpark for that vehicle. Or, they see the resulting speed for that vehicle, vehicle weight/size, and tire size, can infer that the gearing is wrong by experience.
