What is the difference between the "RMSE" and the validation "RMSE" in the Curve Fitting Toolbox?

Hello,
I've been using the curve fitting toolbox to fix a set of point cloud data. In the goodness of fit evaluations, I can see two different RMSE: RMSE and Validation RMSE. Would someone please explain what's the difference between the two RMSEs and why they are different in value?
It feels like the "validation RMSE" is the RMSE error between the actual point cloud surface and the fitted surface. However, if this is the case, then what is the RMSE (or non-validation RMSE)? I can't find a detailed explaination online, so hope someone would help me. Thanks.

Note that in your upper plot figure, your fit data is shown and "RMSE" computed for
and in the bottom one, some fit (validation) data set is taken for your computed fit model and "validation RMSE" is computed for that part of data.
