This was
mostly the case for 23mm tires which were faster on 8 bar, roughly their maximum allowed pressure. The conventional wisdom wasn't wrong during the days of very narrow tires.

What happened in the meantime is that rims and tires both got wider, and a wider tire at the same pressure is effectively stiffer, meaning the optimal pressures went down, while maximum allowed on a 25mm tire is still around 110 psi. So the old ways don't make sense on 25mm tires, and even less on 28mm, but at one point, they did.
