However when we look at the semivariagram fit one of them closely follow the line of fit while the other has a much larger scatter. This means that one of the maps is actually much more accurate then the other.
Statistically, your question is related to the fact that the covariance matrix from the fit of the variogram model is usually disregarded in subsequent analyses. Some time ago i asked about this discarding of the variogram parameters covariance matrix and geostatisticians replied that this source of uncertainty was usually less important than other problems and should not be of much importance.
