The specs on the label isn't what is misleading, the Q&A answer is.
Why quote HTHS at all, in the sense of engine protection for a 30 grade when it's a low value to begin with, compared to allowable limits for the grade.
If an informed reader read that Q&A bit, and knew what the HTHSV of 0w30 AFE was and what the grade limits were, they could easily see that AFE 0w30 HTHSV is closer to the SAE xW20 maximum cP limit than it is to the xw30 cP limit.

Quote:
Characteristics of oil film in high temperature (Comparison of HTHS viscosity)
The oil film is 17 percent thicker than the general 0W30 oil and it could also produce the same thickness to 0W40 and 5W40 in high temperature. It could be used safely
for turbocharged engines which require steadiness when in high temperature. Also extremely low friction characteristics of the base oil will give a great engine response in
both high and low rev.
* Suitable for Toyota 86 FA20 engine
