I do think that specific section is unnecessary. The big draw of the Yengo et al. 2022 is that it found genetic variants that account for nearly the total heritability of height, and it is odd to compare that with Savage et al. 2018 which clearly lacks a similar power. However, doesn't the rest of the article stand fine without it? The point there is that heritability of "intelligence" is notably lower than height. Howe et al. estimated the population heritability of cognitive ability as 23%, which is right in the ballpark of the heritability estimate given by Savage et al. 2018 (h2 = 19-22%). Both of these estimates are still substantially smaller than the heritability height at 38%, and even smaller when comparing the within-sibship heritability (14% vs 34%).
