Because it may not be able to tell if you had the same sample and the
same weights for two commands. It's a precaution measure. Note however
that if you are reasonably knowledgeable to have specified -svy-, then
-suest- should work (at least that's my reading of the help file). An
occasion where you might have -pweight- without other associated
complex survey features (stratification and clustering) is a
relatively odd thing, so basically -suest- invites you to rethink
whether what you are doing is statistically correct, to begin with.
