> the software is incorrectly displaying it as a low pressure warning
The post doesn't specify if the display actually says low pressure, or if the TPMS warning light comes on, which we usually interpret as low pressure (most common case). If it is the TPMS light, I'm sure that's more of an "out of range" warning than "low pressure."
The post specifically says, "It complains about low tire pressure" so I took the author at their word.
But on the other hand, you may be right. Maybe it's just a TPMS light. It's a fun ranty blog post, the author wasn't necessarily being super precise with language =)
But the other other hand, not all TPMS systems can detect overpressure (indirect TPMS only detects underpressure)
