This is probably an effect due to sample size. If they correlate well,
then it would be surprising if a larger sample did not show that they
predicted well for the same features and groups. (Well, if they didn't,
it would certainly be worthy of investigation. But since there have
been a large number of comments indicating that only small numbers of
people have been examined & reported on for the open-ended tests, sample
size appears the most likely reason for the effect.)
