But, broadly speaking, definitely sounds like they didn't take something into account w.r.t. hot tire pressure. Maybe the tire sensors are throwing a warning because the temp is too high, and the software is incorrectly displaying it as a low pressure warning, or... or some other hellish combination of failure.
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."
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)
