I noticed that, but it's in an intro section and isn't clear about what kinds of situations it's discussing. I mean, it's clear than an enemy around a corner has cover against missile or reach attacks. I'd argue the grey box takes precedence for combat rules, and the grey box is pretty precise about how cover is determined.Cover (–2 Penalty to Attack Rolls):
The target is around a corner or protected by terrain. For example, the target might be in the same square as a small tree, obscured by a small pillar or a large piece of furniture, or behind a low wall.
simpleas that...
seems they forgot to add that deermining cover is only used for ranged attacks
from the DMG:
The rules in thePlayer’s Handbook for determining cover are straightforward. A creature that’s around a corner from the attacker, or protected by terrain, has cover.
Some clarification or errata in the grey section would be pretty welcome, though. I can see how it mentions corners in a lot of places, and indeed that could be the intention!!
