Essentially, Holladay is complaining about the lack of water detailing, which is super important to the durability of brick. It doesn't need to be as fancy as his first example, as the link above shows, but you need someone to care about it.
Essentially, the issue building science specialists have with modernist architecture is that it often favors geometric simplicity over proper protection of the materials. Brick can withstand water, to an extent, but without drip edges and other details, it's quickly going to get damaged and ugly.
Note that building science nerds also tend to hate bumpouts and complicated rooflines because the air tightness and insulation details are hard to get right (and usually they just aren't done properly).
