You estimate your model on your original dataset, than you open your
new dataset, create the splines, and predict. -predict- does not know
or care whether you use the same data that where used for estimating
the model. I make this sound as an convenient error in Stata, but it
is actually a feature. (Or it was an error that turned out to be so
useful that someone at StataCorp decided that "yeah, we meant to do
that". We'll never know...)
