The lower we go, the less energy we have. What happens is the following. The Beryllium creates this hybridized orbital SD hybridized which comes from one S and one P an St hybridized orbital. And that orbital, which is a bit slightly higher in energy than our one S of the H atom. So this is the H atom, and this is the one S orbital. And this is the SP hybridized orbital of our Beryllium.
