from the article,

There was an OD4 diode, but it is deleted from the schematics.

this is why providing schematics alone is not sufficient. PinePhone only provides schematics and not board layout and it is entirely possible that they are only loosely related. an imperfect analogy would be providing source but only running a binary compiled by someone else. you can see what they intended to do, but not necessarily what they did.
